+
+ * src/save.c: The "set view" command was incorrectly saved twice.

+2009-06-04 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/mouse.c: The following test script triggered multiple problems.

+
+ * time.c (ggmtime): Counting back from 1.e38 by one year at a time takes

+ text for tics labels, axis labels, key labels, but black title text.
+ Bug #2750114
+
+2009-04-09 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/gplt_x11.c: Filled boxes and filled polygons have different
+ behaviour when the fillstyle is FS_DEFAULT, but the x11 driver was
+ not making this distinction. (caused by patch of 2008-06-22).
+
+2009-03-29 Ethan A Merritt <merritt@u.washington.edu>
+
+ Release 4.2.5
+
+2009-03-28 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/graphics.c (boundary): Reserve room for user tic labels even if
+ the format for autoticks is "".
+
+ * src/set.c (load_tics) src/save.c (save_tics): Do not save or restore

+ Bug #2714997
+
+2009-03-26 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * src/history.c (write_history_list): Indexing istart from 1 otherwise

+ (Lucas Hart)
+
+2009-03-24 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * src/pm3d.c (pm3d_plot): The quadrangles are only prepared but not
+ drawn by this routine in pm3d depthorder mode, thus set_color() should
+ not be called.
+
+2009-03-23 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/win/wgraph.c (Wnd_exec_event): Clean the 2nd parameter sent to
+ gp_exec_event after a keypress. This should fix the problem leading to
+ "protocol error" messages.
+
+2009-03-18 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/wxterminal/gp_cairo.c (gp_cairo_draw_text): Determine the vertical
+ placement of text based on the average value found when the font was
+ selected, rather than on the specific height of this text fragment.
+ Otherwise successive fragments with different height produce an uneven
+ baseline. Bug #2661664
+
+ * src/axis.c (make_tics): Trap case where there were insufficient data
+ to determine axis range. E.g. "set view map; set pm3d; splot {0,1};".
+
+2009-03-15 Ethan A Merritt <merritt@u.washington.edu>
+
+ Increment patchlevel, version strings, documentation dates, and NEWS in
+ preparation for release of version 4.2.5
+
+2009-03-13 Ethan A Merritt <merritt@u.washington.edu>
+
+ * demo/datastrings.dem demo/histograms.dem demo/histograms:
+ Switch demos to use the documented syntax "... title columnhead(2)"
+ rather than the deprecated "... title 2"
+
+2009-03-05 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/graphics.c: Fix assignment of fill patterns to plot boxes and key
+ for columnstacked histograms. Bug #2664732
+
+2009-03-04 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/graphics.c (find_maxl_keys do_plot): The first entry in a list of
+ labels is a placeholder for style information. Do not reserve space for
+ this entry in the key of a columnstacked histogram plot. Bug #2664723
+
+2009-03-02 Ethan A Merritt <merritt@u.washington.edu>
+
+ * term/hpgl.trm term/tgif.trm term/gd.trm:

+2009-03-02 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * term/post.trm (PS_encode_image print_five_operand_image): Fix
+ related to the patch of post.trm from 2009-01-26: images drawn
+ "with rgbimage" must always be drawn as rgb colour images.
+ SF Patch #2613919: postscript outputs colour RGB as palette image
+
+2009-02-25 Ethan A Merritt <merritt@u.washington.edu>
+
+ * term/gd.trm (PNG_text_angle): Force angle to fall in the range

+2009-02-14 Ethan A Merritt <merritt@u.washington.edu>
+
+ * demo/all.dem demo/heatmaps.dem: Add heat maps to demo set.
+
+2009-02-11 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * config/makefile.mgw: Use $(CC) instead of gcc to compile pgnuplot.
+
+2009-02-07 Ethan A Merritt <merritt@u.washington.edu>
+
+ * term/x11.trm (X11_options): Call term->init() rather than X11_init(),
+ since the options routine is shared by x11 and xlib drivers.
+
+2009-02-05 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/util.c (type_udv) src/eval.c (add_udv_by_name) src/fit.c
+ src/plot2d.c: Prevent strange behaviour due to uninitialized field
+ udv_type in a udv entry that has been created but not yet defined.
+ Bug #2556225
+
+ * src/graph3d.c (draw_3d_graphbox): Allow Z axis label in 3D plots
+ to be rotated.
+
+2009-02-02 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * src/mouse.c (lookup_key): Use exact match, otherwise F10, F11, or F12
+ hotkeys bind to F1.
+
+2009-01-28 Petr Mikulik <mikulik@physics.muni.cz>

+ * src/breaders.c (edf_filetype_function): Fix for long headers.
+
+2009-01-27 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * src/pm3d.c (pm3d_plot): Fix for "set pm3d depthorder" ignoring
+ "set pm3d interpolate".
+
+2009-01-26 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * term/post.trm (PS_make_header PS_image): Since the beginning of pm3d,
+ the "/Color def" switched between gray and colour map. Choosing "false"
+ for "Color", the gray map was always selected regardless the use of a
+ custom palette. This led to ambiguities for custom colour palettes if
+ they contain grays only. Thus let postscript choose always colour
+ palette for interpolated colours ('set palette defined', 'set palette
+ file') and colour/gray according to "Color" otherwise ('set palette
+ gray', 'set palette rgb').
+ SF Patch #2516634: custom colormap using postscript term
+
+2009-01-22 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/svg.trm: Back-port changes to svg terminal driver from 4.3 CVS.
+ This adds support for dashed lines, additional color modes,
+ more standard xml syntax for attributes, and a work-around for viewers
+ that fail to correctly inherit <text xml:space="preserve">
+
+2009-01-21 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/fit.c (fit_command): Issue a warning if no fittable parameters
+ are found.
+ Bug #1964774
+
+2009-01-14 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/util.c: Replace the file util.c with the correct file for this
+ CVS branch. Somehow the copy from the 4.3 branch got incorrectly
+ duplicated here.
+
+2009-01-14 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * src/gplt_x11.c (process_event): Change the status bar of a non-active
+ or persistent window only for almost2d plot.
+
+ * src/gplt_x11.c (exec_cmd): Add field almost2d to plot_struct and set
+ it according to sent ALMOST2D.
+
+ * term/x11.trm (X11_text): Send information about ALMOST2D.
+
+ * src/gadgets.h src/mouse.c: Move definition of macro ALMOST2D to

+
+ * config/makefile.mgw: Option to run gdlib-config to determine libraries
+ for linking of gd. Fix link where to download hcw.
+
+2009-01-07 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/util3d.c (edge3d_intersect): Fix long-standing bug in which
+ the z coordinate was clipping against xmax rather than zmax.
+ Bug #2472621
+
+2008-12-27 Allin Cottrell <cottrell@wfu.edu>

+
+2008-12-17 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/x11.trm (parse_driver): Do not overwrite environmental variable
+ GNUPLOT_DRIVER_DIR.
+
+2008-12-14 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/gadgets.c src/gadgets.h src/graph3d.c src/graph3d.h src/save.c
+ src/show.c src/unset.c docs/gnuplot.doc:
+ More work on "set view equal {xy|xyz}'. It now works well for terminals
+ with isotropic coordinate systems, but unfortunately not for x11 or
+ for windows.
+
+2008-12-13 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/emf.trm: Replace assert() statements with int_warn().
+ Fix handling of enhanced text for which the rotation angle is non-zero.
+ Bug #2424595
+
+2008-12-11 Bastian Maerkisch <bmaerkisch@web.de>
+ Axel Thimm <thimm@users.sourceforge.net>
+
+ * configure.in NEWS src/command.c src/gp_hist.h src/graphics.c
+ src/history.c src/plot.c src/readline.c src/readline.h src/show.c
+ src/term_api.h src/term.c (term_initialise):
+
+ ./configure --with-readline=bsd
+ Allow gnuplot to use the NetBSD editline library as an alternative to
+ gnu readline. This adaptation was originally coded by Bastian Maerkisch
+ and subsequently improved by Axel Thimm and by Tormod Volden.
+
+ The routine term_init() is renamed to term_initialise() to avoid
+ conflict with an identically named routine in libedit.
+
+2008-12-11 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/fit.c src/show.c src/variable.c term/pdf.trm:
+ Quiet some compiler warnings.
+
+2008-12-07 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/graphics.c (do_key_sample do_rectangle): Fill style EMPTY
+ should be no fill at all, rather than fill with background.
+ Bug #2345832
+
+2008-12-04 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/datafile.c: Give an error message if the user requests any

+
+ * src/graphics.c (boundary) src/graph3d.c (boundary3d)
+ docs/gnuplot.doc docs/gnuplot.texi:
+ `set {lrbt}margin at screen FRAC` should behave consistently for all
+ four plot borders. Ignore the current value of `set origin`.
+ Bug #2345000
+
+2008-11-27 Ethan Merritt <merritt@u.washington.edu>
+
+ * docs/gnuplot.doc src/gadgets.c src/gadgets.h src/graph3d.c src/save.c
+ src/set.c src/show.c src/unset.c NEWS:
+ The docs say that 'set size ratio' is ignored in 3D; make it so.
+ New option 'set view equal_axes' that forces x and y axes in a 3D plot
+ to use the same scale. This is similar to 'set size square' in 2D.
+ Bug #2004205. Feature request #2006851.
+
+ * src/set.c (prune_dataticks): Fix typo causing ticlabel list corruption
+
+2008-11-19 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/gd.trm (PNG_options): If no information is available about what
+ default scalable font might be available we currently give up and fall
+ back to a built in non-scalable font. Now we try font "arial" before
+ falling back. Who knows, it might even be available.
+
+2008-11-13 Ethan Merritt <merritt@u.washington.edu>
+
+ * docs/gnuplot.doc docs/gnuplot.texi: Update section on color selection
+ to include "lc variable".

+
+2008-10-30 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/axis.c (gen_tics) src/axis.h: Use a more complete test for
+ round-off error when the increment between axis tics is close to the
+ precision of the floating point representation.
+ Bug #2209654
+
+2008-10-27 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/misc.c (lp_parse) src/graphics.c (check_for_variable_color):
+ New colorspec: 'lc variable'
+ Read linestyle index from data column, look up corresponding color.
+ (2D plots only; Version 4.2 handling of variable color in 3D is messy).
+
+2008-10-12 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/plot2d.c (eval_plots): Explicitly set default color of first
+ histogram to linestyle/linetype 0.
+ Bug #2155287
+
+2008-10-10 Petr Mikulik <mikulik@physics.muni.cz>

+2008-10-10 Shigeharu Takeno <shige@iee.niit.ac.jp>
+
+ * src/win/wgraph.c (drawgraph): Work around a Windows clipboard bug by
+ using ExtCreatePen() only for linewidth != 1. The clipboard loses the
+ line color if created with ExtCreatePen(), but not CreatePenIndirect().
+ [sfeam] Is the clipboard problem still present for thicker lines?
+
+2008-10-08 Shigeharu Takeno <shige@iee.niit.ac.jp>
+
+ * src/plot.c (main):
+ Add a command line option -e to execute specified commands:

+
+2008-10-06 Juergen Wieferink <wieferink@freenet.de>

+
+ * src/eval.c src/gp_time.h src/internal.c (f_strftime f_strptime)
+ src/internal.h demo/stringvar.dem docs/gnuplot.doc:
+ Introduce two new functions 'strftime' and 'strptime', which do

+ This has been in 4.3 cvs for 18 months now with no reported problems.

+
+2008-08-16 Ethan Merritt <merritt@u.washington.edu>

+ * term/emf.trm: Provide a separate "dashlength" option.
+
+2008-08-05 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/axis.h src/eval.c: Track min/max range of data on each axis
+ indepently of the current axis range itself. Export to the
+ corresponding variables GPVAL_DATA_{AXIS}_MIN and so on.
+ This is useful all by itself, but also lays the groundwork for
+ implementing "range-frame" borders as per request #2025481.
+
+2008-08-01 Ethan Merritt <merritt@u.washington.edu>
+

+
+2008-07-23 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/mouse.c src/command.c (pause_command) src/command.h:
+ New variant 'pause mouse close' will pause until the plot window is
+ closed. Unlike existing variants, this does not disable mouse-clicks,
+ hotkeys, or zooming. Add wxt to the list of terminals that need a
+ work-around to avoid losing an input character when the plot window
+ is closed.
+
+2008-07-22 Ethan A Merritt <merritt@u.washington.edu>

+
+ * term/post.trm (PS_vector): Work around a bug in ghostscript/gv.
+ If there is a long string of mixed relative/absolute lines without a

+
+ * src/hidden3d.c (store_polygon) src/mouse.c (event_motion):
+ Replace a pair of assert() statements with a flag that prevents mouse

+

+
+2008-05-03 Ethan A Merritt <merritt@u.washington.edu>
+
+ * term/cgm.trm: Clean up terminal code.
+ Use shared routines gp_alloc(), int_expression().
+ Switch to using same set of colors as other terminals (web_color_rgbs).
+ Handle RGB color request by returning closest match to a known color.
+ Don't over-write user colors with each new palette.
+ Decouple dash pattern from line color.
+
+ * term/fig.trm: Extend point types to match standard sequence for the

+ Add a table lookup for font names known to fig, so that the terminal
+ accepts for example 'set term fig font "Palatino Italic, 11"'.
+
+ * src/tables.h src/tables.c (lookup_table_entry): New utility routine

+
+2008-04-27 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/datafile.c (df_tokenise df_read_matrix): If missing or bad data is

+ to NaN if it isn't already, and return to the caller normally.
+ This allows one to leave holes in a matrix data file.
+
+ * src/graphics.c (boundary): The windows and postscript terminals place
+ the xlabel text with the character baseline on the bottom edge of the
+ canvas. This causes any descenders to be clipped. This patch leaves an

+ Track highest data column referred to in an expression.
+
+ * src/datafile.c (plot_option_using): Use info returned by perm_at()

+ Bug #1929227
+
+2008-04-06 Ethan A Merritt <merritt@u.washington.edu>
+

+
+ * src/eval.c (update_gpval_variables) docs/gnuplot.doc: Users can

+
+ * term/cgm.trm (CGM_fillbox CGM_filled_polygon): Move the

+
+2008-02-29 Ethan A Merritt <merritt@u.washington.edu>
+

+2008-02-26 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/graphics.c (map_position place_objects) src/graphics.h src/mouse.c
+ src/color.c: Change map_position() to return (int) x,y rather than

+2008-02-22 Ethan A Merritt <merritt@u.washington.edu>
+
+ * term/pslatex.trm: Include entry point PS_path in the terminal tables

+
+2008-02-20 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/graph3d.c (place_arrows3d): Save/restore the clipping area so

+
+ * src/graphics.c (boundary): Reset the default clipping area to the

+2007-05-28 Ethan Merritt <merritt@u.washington.edu>

+2007-05-25 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/latex.trm: Add an explicit size option; clarify documentation.

+
+2007-05-23 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/svg.trm: Give font sizes explicitly in pt units.
+
+ * term/svg.trm: Subscript/superscripts position must be done using

+
+ * Make a concession to non-compliant svg viewers and clean up the scope

+
+2007-05-09 Ethan Merritt <merritt@u.washington.edu>
+

+
+2007-05-07 Ethan Merritt <merritt@u.washington.edu>

+2007-05-05 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * src/wxterminal/wxt_gui.cpp (wxtThread::Entry):

+
+2007-05-04 Daniel Sebald <daniel.sebald@ieee.org>

+2007-05-04 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/graph3d.c (key_sample_point_pm3d): The sample point in the key

+2007-04-25 Ethan Merritt <merritt@u.washington.edu>
+

+
+2007-04-24 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/x11.trm (X11_text): term_reset() tries to close down all files

+
+2007-04-17 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/post.trm: Change the default to "blacktext" for the TeX-based

+
+2007-04-01 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/util.c (gprintf): Accept the ' format specifier, which

+
+2007-03-21 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * src/graphics.c (boundary): The change of 2007-02-25 overlooked the

+ Bug #1684789
+
+2007-03-21 Ethan Merritt <merritt@u.washington.edu>
+
+ These are mostly trivial patches that went into CVS soon after the
+ code freeze for 4.2
+
+ * src/graphics.c (plot_impulses plot_points plot_dots)
+ src/plot2d.c (get_data store_2dpoint store_label):
+ Allows a third column of data containing color info to be used in
+ 2D plots (points/dots/impulses/labels),
+
+ * term/gd.trm (PNG_image) term/pdf.trm (PDF_image)
+ term/post.trm (PS_image)
+ src/wxterminal/gp_cairo.c (gp_cairo_draw_fillbox gp_cairo_draw_image):
+ Teach gd pdf post and wxt terminals to clip images using the

+
+ * term/pdf.trm (PDF_SetFont): Trap errors from PDF font selection,
+ making it non-fatal.
+
+ * src/axis.c (get_position_default):
+ Reduce the problem of trailing comma after 2D offset.
+
+ * src/graph3d.c (plot3d_impulses): splot with impulses lt rgb variable.
+
+ * src/graphics.c (do_key_sample):
+ If the length of a boxplot sample in the key is set to zero, do not
+ draw it at all. Without this patch, a spurious vertical line appears
+ in the key if the fillstyle includes a border.
+
+ * term/svg.trm (SVG_PathLimit SVG_MoveForced):
+ Avoid ridiculously long paths by limiting total path length to 512.
+
+ * src/util3d.c (draw3d_line_unconditional): Clip line segment.
+ Fixes segfault when line segment endpoint went negative in bitmap.c
+ Bug #1649887
+
+ * src/graph3d.c (do_3dplot draw_3d_graphbox):
+ Add special-case tests to insure that the plot border is drawn either
+ back or front (in front of the grid) when splot_map is set.
+ Bug #1655001
+
+ * term/gd.trm (PNG_vector): Grid lines (linetype 0) were always
+ treated as alternating black/white/black/white. Change this to
+ alternating current_color/transparent/current_color/transparent.
+ Bug #1655001
+
+ * src/set.c (parse_label_options):
+ Make sure that there is a default point type, so that
+ 'set label <n> point' does in fact draw an acceptable point.
+
+ * src/datafile.h src/datafile.c (df_reset_after_error)
+ src/util.c (int_error):
+ The routines in datafile.c use local variables to track the context of
+ expression evaluation; e.g. expressions may only reference data column
+ values inside a `using` statement. But the state of these context
+ variables is corrupted if an error exit bails directly to the command
+ line, thus bypassing the normal execution path. Therefore we provide a
+ routine df_reset_after_error() to be called from int_error().
+
+ * src/eval.c docs/gnuplot.doc:
+ Allow strcol() and shorthand for stringcolumn()
+
+ * src/unset.c (unset_style):
+ Add missing command "unset style line <n>".
+
+ * term/gd.trm (PNG_init):
+ The color palette indexing of the brush is not necessarily the same as
+ that of the main image. Set initial color index to something invalid so
+ that we force an update on first use.
+ Bug #1673316
+
+ * src/term.c (init_term):
+ Normally we initialize the default terminal on program entry. However,
+ if the default is x11 then defer initialization until an actual plot
+ command. This mitigates problems if gnuplot_x11 cannot be started
+ normally, and allows the user to select a different driver in the case
+ that x11 is the default but is broken.
+ Bug #1530601
+
+ * src/win/winmain.c (appdata_directory):
+ WinNT can segfault if APPDATA is missing from the environment.

+2007-02-25 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * src/color.c (draw_color_smooth_box) src/plot3d.c (eval_3dplots):
+ Call setup_tics(COLOR_AXIS, 20) at the same place as setup_tics(...)
+ for all other axes. Until now it was called much later during color box
+ drawing where it could change the colour axis min or max by rounding it

+ (plot_option_array): Use : instead of , for separator between elements.
+ (token2tuple): Use real(const_express()) to parse image parameters.
+ This allows variables to be used in image specs.
+ (plot_option_comma_separated): Changed "comma_separated" to

+
+ * term/pbm.trm (PBM_graphics PBM_options): Decouple 'set size' from

+ * docs/gnuplot-ja.doc docs/faq-ja.tex: Sync Japanese documentation,
+ SF Patch [1519215].
+
+2006-09-23 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/pm3d.c (set_plot_with_palette): It used to be that all plots
+ needing a colorbox had pm3d_color.type == TC_DEFAULT. This is no
+ longer true, so add a more specific check on whether a colorbox is
+ needed. Bugfix.
+
+2006-09-23 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * src/wxterminal/wxt_gui.cpp (wxtPanel::OnSize): Clean floating-point
+ comparison nonsense.
+
+2006-09-22 Juergen Wieferink <wieferink@freenet.de>
+
+ * term/post.trm (PS_vector): To avoid accummulated error in a long
+ series of relative moves or draws, we were issuing a "stroke" command
+ periodically to force an update of the absolute position. This has the
+ bad side affect of resetting the current dot/dash pattern. Fix this so
+ that instead of using "stroke", we simply force an absolute vector
+ before continuing. This avoids accummulated error but does not reset
+ the dot/dash pattern.
+ Bugfix #1542050
+
+2006-09-21 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * configure.in: Bump required version of wxWidgets to 2.5.3 for the
+ wxt terminal.
+
+ * src/wxterminal/wxt_gui.cpp (DrawToDC): Fix double cast warnings.
+ Fix a lazy constructor that seems not to be accepted on all setups.
+
+2006-09-19 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/show.c (disp_value): Force clean printout of "NaN" on save,
+ print, or show commands. Without this, the value is printed as
+ "nan.0", which is not parsable by set or load commands. Bugfix
+ #1544347
+
+2006-09-16 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * configure.in: Rework the checks for cairo and pango so that the error
+ messages are more helpful, mostly by copying the defaults pkg-config
+ messages and making them non-fatal.
+ Revert the minimum version of pango to 1.10.0 but refuse to compile the
+ wxWidgets terminal with pango 1.10.2.
+
+2006-09-16 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
+

+
+2006-08-30 Harald Harders <h.harders@tu-bs.de>

+ exactly as done elsewhere in the code.
+
+2006-08-30 Ethan A Merritt <merritt@u.washington.edu>

+
+2006-08-24 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/plot3d.c (get_3ddata): Increment the current point even if its
+ value is undefined. This allows grid spacing to be maintained, and
+ correctly handles `splot ... using ($1):($2):($3)`.
+
+ FIXME: This is only a partial solution. Deeper problems exist in the
+ handling of missing/NaN/junk data values during input. In particular,
+ gridding is still corrupted in the case of `splot ... using 1:2:3`.
+
+2006-08-23 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/color.c (cbtick_callback): Add handling of text properties

+
+ * src/eval.c (update_gpval_variables): Make it explicit which variables
+ are updated from which context.
+
+ * src/plot.c (main) src/util.c (int_error): Call update_gpval_variables

+
+ Bug #1540398 (last release-critical tracker item)
+
+2006-08-19 James R. Van Zandt <jrvz@comcast.net>
+
+ * term/cgm.trm: update email address
+
+2006-08-19 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/graphics.c: One half of the definition of clip_fill was
+ inadvertently omitted from the patch of 2006-06-04. This fix allows the
+ improved clipping to apply to all filled curves, whereas without it the
+ new clipping code only checked for "closed" filled curves.
+
+2006-08-16 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/gadgets.h: Initialize default histogram title structure to use
+ character units for the title offset. Fixes spurious error if the
+ y axis is log scale.
+
+2006-08-14 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/graphics.c (do_key_sample): Check for terminal support of
+ term->filled_polygon before using it to draw a key sample. Fixes
+ segfault in epson driver (and probably others) if a filled area
+ is assigned an RGB color.
+ Bugfix.
+
+ * src/eval.c (update_gpval_variables): Test for term==NULL, and if so
+ return without doing anything. This prevents a segfault. However, why
+ does the program not trigger a similar segfault elsewhere?
+ Bug #1540398
+
+2006-08-13 Ethan A Merritt <merritt@u.washington.edu>
+
+ * docs/gnuplot.doc: Clarify the argument required by exists(), and
+ provide an example of passing it a string variable containing the

+
+2006-08-13 Petr Mikulik <mikulik@physics.muni.cz>

+
+2006-08-09 Ethan A Merritt <merritt@u.washington.edu>
+
+ * term/post.trm term/PostScript/prologue.ps: Move the pattern-fill
+ background initialization out of the terminal driver and into the

+
+2006-08-09 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * docs/Makefile.in: Revert change from 2006-07-18 (define

+
+2006-08-09 Bastian Maerkisch <bmaerkisch@web.de>
+
+ SF Patch [1505261] wgnuplot: open file-open-dialog in current dir
+
+ * src/win/wmenu.c (SendMacro): Windows XP uses a strange initial
+ directory for the file open dialog. This patch forces the dialog to
+ always open in the current directory. So now, if you change the
+ directory via 'cd', the file open dialog opens where expected.
+
+2006-08-08 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
+
+ * src/show.c (show_version): Fix C99-ism by reintroducing
+ a pair of braces that had been removed.
+
+2006-08-07 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * src/wxterminal/wxt_gui.cpp (wxtPanel::wxt_cairo_create_bitmap):
+ Use a reference instead of a pointer to avoid misusing an undocumented
+ constructor that will be removed in wxWidgets >= 2.7.0.
+
+2006-08-07 Ethan A Merritt <merritt@u.washington.edu>
+
+ * demo/all.dem: Add rectangle.dem to the standard test set.
+
+ * demo/image.dem demo/macros.dem demo/rainbow.dem demo/rectangle.dem:
+ Now that we have the configuration options in GPVAL_COMPILE_OPTIONS we
+ can use this to test for the presence of optional features needed for
+ any particular demo. These particular demos require configuration
+ options that are marked EXPERIMENTAL in version 4.2, so we test for
+ the presence of the feature and if it is missing then we print a
+ warning message and skip the rest of the demo. This allows "make check"
+ to succeed even if the EXPERIMENTAL features are configured out.
+
+2006-08-06 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * docs/gnuplot.doc: Document GNUPLOT_PS_DIR in the list of environment
+ variables.
+
+ * INSTALL: Likewise.
+ Synchronize the output of `./configure --help'.
+ Document the requirements of the wxWidgets terminal.
+
+ * configure.in: Remove detection of libpng, useless since the
+ standalone png driver has been removed.
+
+ * src/Makefile.am (AM_CPPFLAGS); Remove PREFIX and VERSION_MAJOR, those
+ were used by the wxWidgets terminal but are not anymore.
+
+2006-08-05 Ethan A Merritt <merritt@u.washington.edu>
+
+ * tutorial/tutorial.tex: Update version statement to 4.2
+
+ * src/version.c src/version.h: Global (char *)compile_options.

+ * src/show.c (show_version): Save the configuration options string
+ produced for "show version long" in (char *)compile_options. If called
+ as show_version(NULL), do this and nothing else.
+
+ * src/plot.c (main): Call show_version() on program entry in both
+ interactive and non-interactive mode so that it initializes the
+ compile_options string.
+
+ * src/eval.c (update_gpval_variables): New udv GPVAL_COMPILE_OPTIONS
+ that makes the compile_options string available to the user.
+
+2006-08-05 Daniel Sebald <daniel.sebald@ieee.org>
+

+2006-08-04 Ethan A Merritt <merritt@u.washington.edu>
+
+ * term/pdf.trm term/post.trm term/emf.trm term/cgm.trm
+ term/metapost.trm: term->options() should not reset the terminal to
+ its default values if it is called from "set termoption" rather than
+ from "set term".
+ Bug #1534649
+
+ * docs/gnuplot.doc: Fix typo and update example commands to use

+
+ * src/eval.c (update_gpval_variables): Store PATCHLEVEL as a string if

+ versions.
+
+2006-08-03 Ethan A Merritt <merritt@u.washington.edu>
+
+ * term/pdf.trm (PDF_set_color PDF_linetype PDF_filled_polygon):
+ Implement the "mono" option, which up until now has not done anything
+ other than failing to set new linetypes.
+ Bug #1517932
+
+2006-08-03 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * term/PostScript/prologues.h: Regenerated.
+
+ * term/PostScript/ps_header.sh: Force always the same sorting.
+
+ * term/post.trm term/PostScript/prologue.ps: Move "Blacktext {} if" into

+ body.
+
+2006-08-01 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/datafile.c (df_readascii): Allow a string-valued function

+
+2006-07-30 Ethan A Merritt <merritt@u.washington.edu>

+
+2006-07-30 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * term/post.trm: Reword the doc about the prologue files, so that we do
+ not need the #ifdef GNUPLOT_PS_DIR, and so that the use of the

+ always available.
+
+2006-07-30 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * docs/gnuplot.doc: Format norm()/invnorm() info for 80 characters.

+
+ * src/plot.c (main):
+ * src/wxt_gui.c (wxt_atexit):

+
+ SF Patch [1520821] line from ruler to current mouse position if polar
+ distance
+
+ * src/mouse.c term/README: Two new flags for term->set_cursor(flag,...):
+ -3 = draw line between ruler and current mouse position,
+ -4 = don't draw (erase) line between ruler and current mouse position.
+ They are issued when mousing with displayed ruler and showing polar
+ distance or tangent.
+
+ * src/gplt_x11.c: New plot variables ruler_lineto_{on|x|y}, and function
+ DrawLineToRuler(plot) to draw and erase line between ruler and current
+ mouse position. This implements calls of set_cursor(flag,...) for
+ flag=-3 and -4.
+
+ * src/win/wgraph.c: Same as for gplt_x11.c, just with ruler_lineto
+ structure.

+
+2006-07-06 Ethan A Merritt <merritt@u.washington.edu>
+
+ * term/pslatex.trm (EPSLATEX_linetype EPSLATEX_set_color):
+ Keep track of last color and/or linetype set, and filter out

+
+2006-07-06 James R. Van Zandt <jrv@vanzandt.comcast.net>
+
+ * demo/bivariat.dem:
+ - Adjust the step size so the range of integration is an integral

+ - Use Simpson's rule rather than just taking the function value at
+ one end of each step
+ - Add points from the real erf(x) to the first plot, for comparison
+ - For the second plot, define the integrand f(x)=cos(x)
+ That way, the integral is sin(x) instead of being offset by a
+ constant of integration
+ - For the last plot, use "with impulses" to make the pattern more
+ apparent, and because the function is only defined over the integers

+
+2006-06-16 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * src/command.h: Add missing statement about copyright holders (i.e
+ the same as command.c, as command.h was created from this file).
+
+ * src/wxterminal/Makefile.am: New Makefile used to put all the
+ wxterminal source files and bitmaps in the 'make dist' target.
+
+ * src/Makefile.am (SUBDIRS): Add wxterminal to take the new Makefile.am
+ into account.

+ configuration option choices to the output of 'show version long'.
+
+2006-06-15 Shigeharu Takeno <shige@iee.niit.ac.jp>
+
+ * docs/gnuplot-ja.doc docs/README.ja term-ja.diff: Japanese translation
+ of user manual and instructions for building the help system from it.
+
+ * src/win/wgnuplot-ja.mnu /src/win/README.win-ja: Instructions for

+
+2006-06-15 Timothee Lecomte <timothee.lecomte@ens.fr>

+
+ * demo/all.dem demo/html/index.save demo/html/Makefile:
+ Add demo hidden2.dem illustrating 'set pm3d depthorder'.
+
+2006-06-15 Johannes Zellner <johannes@zellner.org>
+
+ * src/save.c src/set.c src/show.c src/tables.c src/tables.h:
+ New option 'set p3md depthorder' to request depth-ordering of
+ pm3d quadrangles.
+
+ * src/graph3d.c: TBOOLEAN pm3d_order_depth tracks the new option.
+
+ * src/pm3d.c src/pm3d.h (pm3d_depth_queue_clear pm3d_depth_queue_flush)

+
+2006-06-14 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * src/color.c (make_palette) src/term.c (term_start_plot):
+ Revert change of 9-Jun-2006, so that we are again optimizing color
+ palette usage by avoiding unnecessary calls to term->make_palette().
+ However, make the PostScript terminal an exception by invalidating
+ the previous palette at the start of every plot.
+
+2006-06-14 Shigeharu Takeno <shige@iee.niit.ac.jp>
+
+ * docs/faq-ja.tex: Japanese translation of faq.tex
+
+ * NEWS docs/Makefile.in: Include faq-ja.tex in list of distributed
+ files, and in NEWS.
+
+2006-06-13 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * demo/stat.inc: Overhaul of routines to add variable arguments,
+ range checking and verify integer when appropriate. The significant
+ change is forcing some input vars to be an integer, rather than casting
+ them to int() in the formulae. (There are proper plot styles like
+ "steps" to work with discrete r.v.s.)
+
+ * demo/prob.dem: Modified the discrete r.v. examples to look more like
+ a mass function or scaled impulses. More varied examples to show
+ various plotting features.
+
+ * demo/prob2.dem demo/random.dem: Add input variables to p.d.f. and
+ c.d.f. functions. Added new Maxwell demo to random.dem.
+
+ * docs/gnuplot.doc: Added adjective "normalized" to igamma()
+
+2006-06-13 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/gplt_x11.c: Move export selection flags outside the the
+ USE_MOUSE conditional code. Bug #1505704
+
+ * src/term_api.h: DEFAULT_LP_STYLE_TYPE to lt -1 (makes arrows
+ default to black rather than red).
+
+
+2006-06-13 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * configure.in src/Makefile.am src/makefile.awc src/makefile.all:
+ Add a configuration mechanism for including binary.c in list of
+ gnuplot sources when appropriate.
+
+ * src/bin_hook.c: Remove from source tree.
+
+2006-06-13 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * src/win/wtext.c:
+ * src/win/wgraph.c:
+ * src/wxterminal/wxt_gui.cpp:
+ * src/wxterminal/wxt_gui.h:
+ * src/wxterminal/wxt_term.h:
+ Fix failures when compiling the wxWidgets terminal with
+ --disable-mouse, by putting more code and declarations inside #ifdef
+ USE_MOUSE ... #endif
+
+2006-06-12 Ethan A Merritt <merritt@u.washington.edu>
+
+ * configure.in: Move options marked EXPERIMENTAL to the end of the
+ configuration summary printout. Remove EXPERIMENTAL label from
+ string variables.
+
+2006-06-11 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * demo/utf8.dem: Issue a 'reset' at the end of the file, as other demos
+ do.
+
+ * src/wxterminal/gp_cairo.c (gp_cairo_draw_text): Use the Symbol to
+ Unicode conversion step, as for the enhanced text mode.
+ (gp_cairo_enhanced_flush): Small cleanup and fix a forgotten free().
+
+ * term/wxt.trm (TERM_HELP): Document the font requirements properly, in
+ particular how the Symbol font is handled and where the fonts are taken
+ from. Layout the whole help text so that lines are smaller than 80
+ characters.
+
+2006-06-11 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * src/eval.h: Added number of variables to user defined function struct.
+
+ * src/command.c (define): Recorded number of variables into udf entry.
+
+ * src/parse.c (add_is_udf, is_ud_functin, add_udf):
+ Slight rearranging of functions to allow code reuse.
+
+ * src/parse.c (parse_primary_expression): Check if function used in
+ command is user defined. If so, verify number of variables is correct.
+
+ * src/internal.c (f_call, f_calln): Added tests to catch variable
+ mismatch at time of evaluation.
+
+2006-06-10 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * docs/Mafefile.in (CORETERM): Add wxt.trm in the list of
+ terminals.
+
+ * docs/gnuplot.doc : Add mentions of `wxt` among other terminals when
+ useful (mouse, raise, lower, image, set_output, fillstyles).
+
+ * src/wxterminal/wxt_gui.cpp:
+ Fix compilation with --disable-with-image.
+
+ * src/wxterminal/wxt_gui.h:
+ Fix compilation with --disable-with-image.
+ Cleanup includes.
+
+ * src/wxterminal/gp_cairo.c
+ (gp_cairo_draw_polygon): Replace malloc by gp_alloc.
+ (gp_cairo_draw_image): Likewise.
+ (gp_cairo_convert_symbol_to_unicode): Likewise.
+
+2006-06-09 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/eval.c src/eval.h src/internal.c src/internal.h src/parse.c
+ src/standard.c src/standard.h docs/gnuplot.doc NEWS:
+
+ Deprecate built-in pseudo-function `if defined(foo)`
+ Replace it with string function exists("foo")
+ The previous version (defined) tried to bypass normal expression
+ parsing, but succeeded only for the simplest cases. This variant,
+ although deprecated, is still supported by BACKWARDS_COMPATIBLE.
+ The new version handles the full general case by using string variables.
+ Bugfix: #1497957
+
+ * src/color.c (make_palette): Revert optimization (18 Mar 2006) that
+ only sent palette information for a plot if it had changed since the
+ previous plot. This doesn't work for PostScript output, because the
+ pages may be viewed out of order. Bugfix.
+
+2006-06-08 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * src/wxterminal/gp_cairo.h:
+ * src/wxterminal/wxt_plot.h:
+ * src/wxterminal/wxt_term.h:
+ Remove "extern" for functions.
+
+2006-06-07 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * configure.in (--with-wx-config=PATH): Fix wrong variable name.

+ Remove hotpost arguments, take hotspot coordinates from the XPM files.
+ (wxtApp::OnInit): Update calls to LoadCursor.
+
+ * src/wxterminal/gp_cairo.h (current_xmax): Rename to the more
+ meaningful device_xmax.
+ (current_ymax): Rename to device_ymax.
+ * src/wxterminal/gp_cairo.c: All callers changed.
+ * src/wxterminal/wxt_gui.cpp: Likewise.
+
+2006-06-06 Ethan A Merritt <merritt@u.washington.edu>
+
+ * configure.in src/setshow.h config/config.*: Move definition of
+ BACKWARDS_COMPATIBLE into config.h and the various config.* files rather
+ than setshow.h so that it is visible to all the source files.
+
+2006-06-06 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * src/wxterminal/gp_cairo.c (device_y): Fix computation of

+
+ * src/graphics.c (two_edge_intersect) Remove old debugging code.
+
+ * src/graphics.c (edge_intersect plot_filled_curves): Bugfix.
+ Fix clipping of filled curves. When a curve leaves the plot and
+ reenters via a different plot edge, we must add dummy points at the
+ intervening plot corners.
+
+ * src/graphics.c (fill_missing_corners): New routine to support
+ clipping of filled areas defined by a bounding curve.
+
+2006-06-01 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/unset.c (reset_command): Abandon the idea of automatic garbage
+ collection for undefined user variables. The problem with this is that
+ user-defined functions may still hold pointers to them for later use.
+ E.g.: f(x) = a+b; reset; print f(1) - oops, no more a or b.
+ Bugfix.
+
+ * demo/world.dat: Rearrange line segments to make more continuous
+ boundaries. Now it almost works for filledcurves.
+
+2006-05-29 Michael Ritzert <ritzert@t-online.de>
+
+ * term/Makefile.am.in: Look for the postscript files to be installed
+ relative to $(srcdir).
+
+2006-05-26 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/gadgets.c (clip_point): The code comments incorrectly described
+ the bit values returned by clip_point().
+
+2006-05-24 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/gplt_x11.c: Treat LT_AXIS linetype as dotted even if the
+ terminal is 'set term x11 solid'. Do not try to set dash type or
+ linewidth for LT_BACKGROUND because this will underflow the type arrays.
+ Bugfix.
+
+ * share/Gnuplot.app-defaults: Comment out settings for *ctrlq *raise
+ and *background so that the default remains the same as having no
+ app-defaults file.
+
+2006-02-23 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * term/wxt.trm (TERM_HELP): Fix typos, thanks to Shigeharu Takeno.
+
+2006-05-22 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * term/vgagl.trm (VGAGL_init_keytable): Fix bug #1492341 by
+ replacing sizeof() on an array of int (which gives an overflow
+ by writing four times more than the size of the array) by the
+ actual size of the array (KEYTABLE_SIZE).
+ (VGAGL_truecolor): Declare as a TBOOLEAN instead of an integer,
+ do not use the enums yes and no but TRUE and FALSE.
+ (VGAGL_processing_graphics_events): Likewise.

+
+2006-05-21 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
+
+ * term/win.trm (HELP): Got rid of some tabs.
+
+ * docs/gnuplot.doc: Fixed some blank-only lines.

+ Sebald.
+
+2006-05-20 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * src/color.h (colorspec_t) [EXTENDED_COLOR_SPECS]: Declare the

+
+2006-05-20 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/gplt_x11.c term/x11.trm: Allow user control of solid/dashed line
+ setting via the usual three mechanisms
+ new X resource gnuplot*dashed: on
+ from command line `gnuplot -dashed ...`
+ from gnuplot command `set term x11 {dashed|solid} ...`
+
+ * term/x11.trm: Bugfix: persist/raise/dashed terminal settings should
+ not be conditional on mouse support.
+
+2006-05-20 Ethan A Merritt <merritt@u.washington.edu>
+
+ * share/Gnuplot.app-defaults share/Makefile.am:
+ New X resources file, intended for installation in the system's

+ Bug #1376604.
+
+2006-05-19 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * src/wxterminal/gp_cairo.c (gp_cairo_draw_enhanced_text):

+ (gp_cairo_end_polygon): Remove useless comment.
+ (gp_cairo_convert_symbol_to_unicode): Change C++-style

+2006-05-18 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * src/Makefile.am (AUTOMAKE_OPTIONS): Remove 'subdir-objects',
+ not mandatory.
+
+ * configure.in (enable_wxwidgets): Remove test AM_PROG_CC_C_O,
+ not needed now that 'subdir-objects' is not used.
+
+ * src/wxterminal/wxt_gui.cpp (wxt_waitforinput) [_Windows]:
+ Rework event processing to avoid code duplication and handle
+ more cases (pause, etc.).
+ (wxt_waitforinput_pause) [_Windows]: Removed.
+ (wxt_terminal_events) [_Windows]: New routine to process
+ pending events from the wxWidgets terminal when it is selected
+ and initialized. Its return code is used to stop a pause.
+ (wxt_set_font): Use reasonable defaults for font name ("Sans")
+ and size (10) instead of the wxWidgets system settings. It
+ avoids to choose the inappropriate Courier font on Windows,
+ where it is used by the console-like window.
+
+ * src/wxterminal/wxt_term.h (wxt_waitforinput_pause):
+ Remove declaration.
+
+ * src/wxterminal/wxt_plot.h (wxt_terminal_events):
+ Declaration.

+
+2006-05-15 Bastian Maerkisch <bmaerkisch@web.de>
+
+ * config/makefile.os2: Define GIF_ANIMATION and HAVE_PDFLIB_H.
+
+ * config/config.os2: Sync to config.h created by `configure`. Define
+ EAM_OBJECTS, GP_STRING_VARS = 2, HIDDEN3D_VAR_PTSIZE.
+
+ * src/os2/gclient.c (DisplayClientWndProc): Filter out WM_MOUSEMOVE
+ events when the mouse hasn't been really moved. This eliminates
+ excessive calls to gp_exec_event(GE_motion, ...) and subsequent
+ unnecessary redraws of the plot.
+
+2006-05-13 Bastian Maerkisch <bmaerkisch@web.de>
+
+ * config/makefile.nt: Make sure that the same (basic) compiler options
+ are used for compiling wgnuplot and pgnuplot. This is necessary since
+ they both contain version.c.
+
+ * src/stdfn.h src/win/winmain.h src/win/wpause.c: Implementation of a
+ non-blocking sleep function (gnuplot's 'pause' command) for windows.
+
+ * term/win.trm (WIN_options, help text):
+ Accept font request strings of the form
+ set term win ... font "<fontface>,<fontsize>"
+ Previous syntax
+ set term win ... "<fontface>" <fontsize>
+ remains valid as well. Update documentation.
+
+ * src/os2/4allterm.cmd: Fix broken argument parsing. Convert end of line
+ to CR/LF pairs. This is a must for the script to be readable by the OS/2
+ REXX interpreter.
+
+ * docs/doc2ipf.c docs/titlepag.ipf:
+ - Increase depth of table of contents from 5 to 6. This fixes
+ "unknown reference" errors during compilation.
+ - Only replace '.' in first column by ipf tag, it's not needed
+ otherwise.
+ - Add an index: interactive help ('?') and explicit index entries ('=')
+ are supported.
+ - Table layout improvements:
+ - omit table frame and horizontal lines
+ - add additional horizontal spacing around table entries (1 char)
+ - omit horizontal rules '_' (troff command)
+ - entries are only interpreted as troff commands if they start with
+ '.' and do not contain a table separator
+ - try to filter out ipf tags when calculating column widths
+ - always assume troff header at beginning of table. This fixes
+ coloring of table headers, which has been broken since 17 Jun 1998
+ - Change handling of paragraphs and verbatim sections: successive empty
+ lines only yield one new paragraph :p. This eliminates large empty
+ spaces (especially in front of tables).
+ - End sections with an empty paragraph instead of starting with an empty
+ paragraph. Eliminates empty space at beginning of section and (still)
+ ensures non-empty sections.
+ - Optionally add additional reference panels to make navigation with
+ IBM's online viewer easier. Controlled by #define IPF_MENU_SECTIONS.
+ - Add a title page (new file titlepag.ipf).
+
+2006-05-12 Ethan A Merritt <merritt@u.washington.edu>

+
+ * term/pslatex.trm (PSTEX_common_init): Avoid warning by making
+ compile-time test an #if rather than an if.
+
+ * config/makefile.mgw: Change this to expect MSYS tools to be used
+ instead of the older native MINGW32 ports. Necessitates some
+ workarounds for MSYS quirks.
+ (HCWPATH): Uncomment one definition, provide a usable default,
+ remove the other.
+ (pgnuplot.exe): Needs -HAVE_STDBOOL_H to avoid a warning.
+ ($(HELPFILE)): Use `-' instead of `/' for $(HCW) options, to avoid

+ (doc2rtf.exe, doc2tex): Strip trailing `/' off macros holding

+2006-04-28 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * src/gplot_x11.c (UNSET, no, yes): Remove enum declaration.

+
+2006-04-27 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * configure.in src/Makefile.am: Change PKG_MAJOR to
+ VERSION_MAJOR to avoid a conflict with pkg-config macros.
+ They will be used with cairo, pango, and gtk+ for the wxWidgets
+ terminal.
+
+2006-04-27 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
+
+ * src/plot2d.c (get_data): Initialize further elements of df_data
+ depending on plot style, so datafile module can parse absolute
+ time/data for xlow etc. Similar fix for handling 'set ydata time;
+ plot "-" u 2'.
+
+ * src/plot3d.c (eval_3dplots): Fix for 'set zdata time; plot "-" u
+ 2'. Replicate realloc size fix from get_data (--> 2006-03-28)
+ here.
+
+2006-04-26 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * docs/gnuplot.doc (fit control environment): Fix mention of
+ command 'set fit logfile'.
+
+2006-04-25 James R. Van Zandt <jrv@vanzandt.comcast.net>
+
+ * term/cgm.trm (CGM_filled_polygon): Allow filled polygons with up
+ to 8190 vertices (was only 50). Also, allocate the
+ polygon/polyline array from the heap, so it only takes space if
+ the CGM terminal is used.
+
+ * term/cgm.trm (CGM_set_color): access colorspec->value only
+ for type=TC_FRAC when it is defined.
+
+2006-04-25 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * src/win/wgnuplot.hpj (COMPRESS): New option, enables compression
+ of the generated .hlp file.
+ (LCID): New option, fixed the language of generated help files to
+ English. Hopefully this will avoid incompatibilities like the one
+ observed with the first binary release of 4.0 for Win32.
+
+2006-04-24 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * src/graphics.c (plot_image_or_update_axes) config/config.cyg
+ config/config.mgw config/config.nt config/config.os2 configure.in:
+ Removed all use of WITH_IMAGE_VERIFY_ALL_PIXEL_LOCATIONS and any
+ code associated with verifying pixel locations in the grid.
+
+2006-04-19 Ethan A Merritt <merritt@u.washington.edu>
+
+ * term/post.trm (PS_set_font): Do not write font change commands
+ into the PostScript output stream of the TeX terminal variants
+ (epslatex, pstex, pslatex). All font handling is done via the TeX
+ output stream. Bug #1472260
+
+ * demo/html/Makefile demo/html/index.save
+ demo/html/gnuplot_demo.css: Update html display of gnuplot demos.
+
+2006-04-18 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/graphics.c (plot_c_bars) src/plot2d.c (eval_plots): Allow
+ user to control the width of whiskerbars on candlestick plots.
+ plot <foo> with candlesticks {whiskerbars {<width>}}
+
+ * demo/utf8.dem: Provide a demo for use in testing UTF-8 support
+ by gnuplot terminals. This demo will only produce reasonable
+ output on a terminal that supports UTF-8 and a current UTF-8
+ encoded font with the relevant character maps.
+
+2006-04-17 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/color.h: Add comments to document the meaning of TC_* flag
+ values.
+
+2006-04-16 Ethan A Merritt <merritt@u.washington.edu>
+
+ * term/aquaterm.trm: Correct typos in help text.
+
+ * src/set.c (set_object): Fix segfault on incomplete command
+ 'set obj <new>'.
+
+ * src/term.c (init_terminal): Keep initial terminal setting in
+ GNUTERM even if it did not actually come from environmental
+ variable GNUTERM.
+
+2006-04-14 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/term.c (change_term init_term): Save value of GNUTERM into a
+ user-defined variable on entry. Use only first word of GNUTERM
+ when calling change_term. This allows GNUTERM to contain extended
+ terminal specs, e.g. setenv GNUTERM "png truecolor transparent".
+
+2006-04-12 James R. Van Zandt <jrv@debian.org>
+
+ * term/cgm.trm (CGM_point): Update cgm_current.edge_visibility
+ before cgm_current.edge_color (was displaying some point symbols
+ with incorrect edge colors).
+
+2006-04-10 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/graph3d.c (draw_3d_graphbox): Fix bug introduced when adding
+ newpath/closepath around the border of 3D plots with 'set view map'.
+ The top border was not getting drawn, and the individual border
+ components were not being considered separately.
+ Also, when in 'set view map' mode, honor 'set border {front|back}'.
+
+ * src/graphics.c (plot_border) src/gadgets.h: Similar bugfix in 2D.
+
+ * src/misc.c (lp_parse): Don't fall into a recursion trap in the
+ case that 'set style incr user' and 'set style line <foo> lt <baz>'.
+ This should set the linetype of <foo> to <baz> even if <baz> itself
+ has been assigned as another line style.
+
+2006-04-08 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/standard.c (f_tanh): Fix a two-fold error in bounds checking for
+ tanh(). Bug #1452627
+
+2006-04-08 Bastian Maerkisch <bmaerkisch@web.de>
+
+ * src/win/pgnuplot.c: Patch for SF bug [1232950] "-persist option does
+ not work in Version 4.0.0 (Windows)". Omit sending `exit` from pgnuplot
+ to wgnuplot when `-persist` is given on command line.
+
+2006-04-08 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * src/set.c (set_palette_file) docs/gnuplot.doc: Binary palette files
+ are supported as well. Example:
+ set palette file "palette.bin" binary record=64 using 1:2:3
+
+2006-04-08 Bastian Maerkisch <bmaerkisch@web.de>
+
+ * config/config.os2: Define more features.
+
+ * config/makefile.os2:
+ - add a list of required/recommended tools and libraries,
+ - make use of pre-built version of libgd from hobbes.nmsu.edu,
+ - change requirements for newer versions of PDFlib,
+ - replace shell script to create allterm.h by 4allterm.cmd in Rexx.
+
+ * src/os2/4allterm.cmd: New Rexx script to create allterm.h, much faster
+ than previous code and does not require the unix tool chain to be
+ installed.
+
+2006-04-07 laboratoryman <laboratoryman@users.sourceforge.net>
+
+ * src/term.c (test_term): No terminal currently implements any head
+ fill style (curr_arrow_headfilled) other than 0/1/2. So don't use 3 as
+ a test case.
+
+2006-04-05 Ethan A Merritt <merritt@u.washington.edu>
+
+ * term/svg.trm: New line-join terminal option {rounded|butt},
+ with support for smooth joining of closed polygons via the recently
+ added newpath()/closepath() mechanism.
+
+ * src/gadgets.c (draw_clip_arrow): Provide a routine in the core
+ code that clips arrow head/tail to the canvas boundaries. This means
+ we don't have to do the clipping in do_arrow(), which has been messy.
+
+ * src/graph3d.c (plot_arrows3d plot3d_vectors)
+ src/graphics.c (place_arrows do_key_sample get_arrow)
+ Draw arrows using new routine draw_clip_arrow.
+ Addresses bug #1348015 and others.
+
+ * src/term.c (do_arrow): Add a note that the clipping here is now
+ redundant, and can be removed. Defer removal to a separate patchset.
+
+2006-04-04 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/plot2d.c (eval_plots): Fix inadvertant breakage due to an
+ accidentally deleted call to arrow_parse().
+
+2006-04-04 Harald Harders <h.harders@tu-bs.de>
+
+ * src/term.c (do_arrow) src/term_api.h docs/gnuplot.doc
+
+ * src/graphics.c (get_arrow plot_boxes plot_vectors)
+
+ * src/misc.c (arrow_use_properties) src/show.c (show_arrow):
+ Add an option "backhead" to arrow style that reverses the sense
+ of the arrow. Modify flags to indicate the forward arrowhead and
+ the backward arrowhead separately, so "heads" sets both flags.
+ Patchset #1318546
+
+2006-04-04 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/term_api.h src/term.c (newpath closepath) term/README:
+ Define a new terminal entry point term->path(foo), and wrapper routines
+ newpath() == term->path(0); closepath() == term->path(1).
+ These are needed to ensure smooth line joins at the ends of a closed
+ path in PostScript-like terminals.
+
+ * src/graph3d.c (do_3dplot draw_3d_graphbox)
+ * src/graphics.c (do_plot plot_boxes plot_cbars do_key_sample)
+ * src/graphics.c (plot_border) src/color.c (draw_color_smooth_box):
+ Enclose the vector commands that draw rectangles with a
+ newpath()...closepath() pair. This guarantees a smooth join for the
+ plot boundary, the key box, colorbox, boxes, and candlesticks.
+
+2006-04-04 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/gplt_x11.c (gpXLoadQueryFont): When trying to load a multibyte
+ fontset, treat "missing charsets" as a non-fatal warning. This seems
+ necessary in order to handle en_US.UTF-8 and similar locales, which
+ claim to require many exotic but trivial charsets. Normally these are
+ not needed, so it should not be a fatal error if they are missing.
+ Bug #1458525
+
+ * term/x11.trm: Increase maximum allowed length of font names.
+
+2006-04-04 Ethan A Merritt <merritt@u.washington.edu>
+
+ * misc.c (lp_use_properties lp_parse): In "set style increment user"
+ mode, an explicit linetype should be interpreted as a call for the
+ corresponding line style. But if there is none, we should load a
+ description of the linetype rather than failing to initialize the
+ lp_style_type at all.
+
+2006-03-28 Lars Hecking <lhecking@users.sourceforge.net>
+
+ * docs/gnuplot.texi: Regenerated after recent documentation
+ updates.
+
+ * term/Makefile.am.in: Add PostScript directory to EXTRA_DIST. Add
+ uninstall support. Rename install target to install-data-local
+ (don't use automake-generated targets in Makefile.am) and add
+ $(DESTDIR) support.
+
+2006-03-28 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * config/makefile.oww (CPPFLAGS): Added -DEAM_OBJECTS.
+
+ * src/plot2d.c (get_data): Avoid small size increments on
+ reallocation --- at least double, and add another 1000 entries for
+ good measure.
+
+2006-03-28 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ Revised handling of Windows "app data" and home directory
+ settings by Bastian Maerkisch.
+
+ * src/win/winmain.c: WANT_GET_DLLVERSION hardcoded active.
+ (CSIDL_APPDATA): Provide fallback definition.
+ (ShutDown): Removed ancient cruft.
+ (appdata_directory): New function. Dynamically attach to
+ shell32.dll and ask it for the "application data" directory.
+ (WinMain): Have get_user_env() take care of finding $HOME.
+ INIFILE_IN_APPDATA hardcoded.
+
+ * src/win/wcommon.h (INIFILE_IN_APPDATA, WANT_GETDLLVERSION):
+ Definitions removed, hardcoded active now.
+ (appdata_directory): Added prototype.
+
+ * src/plot.c: Added #includes of win/wgnuplib.h, win/wcommon.h.
+ (get_user_env) [WIN32]: Call helper routine to find Windows'
+ "application data" directory.
+
+2006-03-27 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/plot2d.c (cp_alloc) src/plot3d.c (sp_alloc): Initialize the
+ line style, arrow style, and fill style fields of each new plot to
+ something reasonable.
+
+2006-03-26 Ethan A Merritt <merritt@u.washington.edu>
+
+ * NEWS: List various new features added since last October.
+
+ * src/gplt_x11.c: Store text rotation angle internally as a double.
+
+2006-03-26 Ethan A Merritt <merritt@u.washington.edu>
+
+ SourceForge patchset #1143563 "Place arbitrary objects in plots".
+ This patchset introduces a general infrastructure for placing
+ individual geometric objects, similar to "set label" and "set arrow".
+ However the only objects implemented at this point are rectangles.
+
+ set object <tag> rectangle
+ {from <position> {to|rto} <position>
+ | center <position> size <w>,<h> | at <position> size <w>,<h>}
+ {front|back|behind} {fc|fillcolor <colorspec>} {fs <fillstyle>}
+ {default} {lw|linewidth <width>}
+
+ set style rectangle {front|back} {fillcolor <colorspec>}
+ {fs <fillstyle>} {lw|linewidth <lw>}
+
+ * configure.in: Configuration option: ./configure --enable-objects
+ Conditional compilation flag EAM_OBJECTS
+
+ * demo/rectangle.dem docs/gnuplot.doc

+ Infrastructure.
+
+ * src/graph3d.c (do_3dplot) src/graphics.c (place_rectangles do_plot)
+ src/graphics.h: Shared routine to place rectangles in 2D and 3D.
+
+ * src/save.c (save_rectangle) src/set.c (set_object set_rectangle)
+ src/unset.c (unset_object delete_object unset_style_rectangle)
+ src/save.h src/show.c: General bookkeeping for objects.
+
+2006-03-25 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/graphics.c (plot_c_bars): Re-order the lines making up a
+ candlestick so that line-joining terminals have some chance of
+ recognizing that the body is a closed rectangle.
+
+ * term/PostScript/prologue.ps: Add a shorthand for closepath.
+
+ * src/graph3d.c src/graph3d.h: New routine map3d_position_double() will
+ be used by "set object" code.
+
+ * src/color.c (draw_color_smooth_box): Use new routine
+ map3d_position_double to avoid a mismatch of parameter types.
+
+ * src/unset.c: Replace "set no<foo>" with "unset <foo>" in comments and
+ error messages; i.e. make them match current syntax.
+
+2006-03-24 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/datafile.c: Remove vestigial comments about df_timecol[].
+
+2006-03-24 Ethan A Merritt <merritt@u.washington.edu>
+
+ * configure.in term/Makefile.am.in term/PostScript/*.ps
+ term/post.trm (PS_common_init PS_dump_prologue_file):
+
+ Install and maintain PostScript prologue and character encoding files
+ in a separate directory, external to the gnuplot executable. This
+ removes a large chunk of text from the postscript driver, and allows
+ local customization, editing, or patching of the postscript
+ configuration. The directory in which these files are stored is taken
+ from config.h: #define GNUPLOT_PS_DIR
+ but may be replaced at runtime by an environmental variable of the same
+ name, or by a "set loadpath" command inside gnuplot.
+ This change should result in no change to the postscript files output
+ by gnuplot.
+
+2006-03-24 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/datafile.h src/datafile.c: Allow an input field expected to be
+ a time format to be in quotes. Previously anything in quotes was
+ assumed to be invalid as a numerical value.
+
+2006-03-23 Ethan A Merritt <merritt@u.washington.edu>
+
+ * docs/gnuplot.doc: New option "set style increment {user|default}"
+
+ By default, successive plots within the same graph will use successive
+ linetypes from the default set for the current terminal type.
+ However, choosing the "user" option allows you to step through
+ user-defined linestyles rather than through the default line types.
+
+ * src/gadgets.c src/gadgets.h: Global flag TBOOLEAN prefer_line_styles.
+
+ * src/save.c src/set.c src/show.c src/tables.c src/tables.h:
+ Save/set/show preference for line styles rather than linetypes.
+
+ * src/plot2d.c (eval_plots) src/plot3d.c (eval_3dplots):
+ If (prefer_lines_styles) then autoincrement successive plots by line
+ style rather than linetype.
+
+ * src/misc.c: Missing line style is non-fatal error.
+
+2006-03-23 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/misc.c (lp_parse): Allow "bgnd" as shorthand for "lt -3".
+
+2006-03-23 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * demo/pm3dcolors.dem: Make one example more happy.
+
+2006-03-22 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/unset.c (unset_axislabel): Fix memory leak from failure to
+ free axis labels.
+
+2006-03-22 Timothee Lecomte <timothee.lecomte@ens.fr>
+
+ * src/gplt_x11.c (handle_selection_event): Fix typo in debug code.
+
+2006-03-19 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * src/graphics.c (boundary): Avoid strchr() on NULL x axis label
+ text.
+
+2006-03-18 Ethan A Merritt <merritt@u.washington.edu>
+
+ Daniel Sebald has pointed out that when the same plot is being redrawn
+ repeatedly, for instance during interactive rotation of 3D plots, the
+ process is noticibly slowed by resending the color palette on each
+ refresh. The following set of changes insures that the palette is only
+ sent if something has changed.
+
+ * src/color.c (make_palette): Do not call term->make_palette() unless
+ either (a) the palette has changed, (b) the terminal has changed, or
+ (c) the output device has changed. New routine invalidate_palette()
+ is available to signal that one of these conditions has occurred.
+
+ * src/set.c (set_output set_palette set_palette_defined):
+ Call invalidate_palette(). Also fix a memory leak.
+
+ * src/term.c (change_term): Call invalidate_palette().
+
+2006-03-17 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * src/gplt_x11.c (exec_cmd): Realigned conditional code to allow
+ compilation with ./configure --with-image --disable-binary-x11-polygon.
+ Fix conditional test associated whith ./configure --disable-with-image.
+
+2006-03-17 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * src/fit.c (splitpath): Reorder tests avoid possible read of
+ uninitialized memory.
+
+ * src/alloc.c (gp_alloc): Cast to (generic *)
+ (checked_free): Introduced new local variable to reduce number of
+ horrible casts.
+
+ * src/hidden3d.c (build_networks): Initialize lp_style from
+ lp_properties, regardless of whether the plot supposedly has point
+ symbols drawn or not. Needed because PM3D drops stuff inside that
+ struct.
+
+2006-03-17 Shigeharu Takeno <shige@iee.niit.ac.jp>
+
+ * term/aquaterm.trm: Correction of misprints.
+
+2006-03-16 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/set.c (set_tic_prop): Another bandaid to protect against
+ int_error() from inside try_to_get_string(). Bug #1434633.
+
+2006-03-15 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/plot3d.c (get_3ddata): Reorder code so that mutually exclusive
+ conditions are handled in an if/elseif/else construct. No actual change
+ in behavior, but it quiets valgrind warning messages.
+
+ * term/post.trm: Prevent segfault if someone passes off an undefined
+ variable as an epslatex header. This is a bandaid rather than a true
+ fix, but it's better than segfaulting. The true problem is that an
+ int_error() exit from expression parsing bypasses proper cleanup of
+ storage for string variables, and also fails to return NULL to the
+ caller. Bug #1434633.
+
+2006-03-15 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * src/datafile.c (plot_option_comma_separated): Found by valgrind.
+ Set an uninitialized tuple value to 0.0.
+
+ * src/set.c (parse_histogramstyle): Found by valgrind.
+ Set an unitialized text label to EMPTY_LABELSTRUCT
+
+2006-03-11 Ethan A Merritt <merritt@u.washington.edu>
+
+ * demo/html/index.save demo/html/Makefile: Add animate2 to the list
+ of webified examples.
+
+2006-03-11 Bastian Maerkisch <bmaerkisch@web.de>
+
+ * term/pm.trm src/term_api.h src/mouse.h src/mouse.c src/plot.c
+ src/set.c src/unset.c: Cleanup of the OS/2 menu stuff communicating
+ gnuplot -> gnupmdrv. This eliminates some 'extern's in C files and moves
+ code specific to pm terminal to pm.trm.
+ 1. Remove update_menu_items_PM_terminal() from mouse.c.
+ 2. Rename send_gpPMmenu() in mouse.c to PM_set_gpPMmenu() and move the
+ actual communication with gnupmdrv to new routine
+ PM_update_menu_items() in pm.trm.
+ PM_set_gpPMmenu() now only updates the gpPMmenu struct.
+ 3. Replace all calls to update_menu_items_PM_terminal() with calls to
+ PM_update_menu_items().
+ 4. Removed multiple definitions of PM_intc_cleanup() in plot.c and
+ pm.trm to term_api.h.
+
+2006-03-11 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/datafile.c (df_open): If a requested input data file is missing,
+ issue a warning and continue. The old behaviour was to issue an error
+ and bail to the command line. df_open() now returns a negative number
+ if the requested file cannot be opened. Callers must test for error
+ return.
+
+ * src/plot2d.c (eval_plots): If a requested file is missing or empty,
+ create an empty plot structure for it, but plot other functions or
+ datafiles as usual. May not work for some combinations of missing
+ binary input files.
+
+ * src/plot3d.c (eval_3dplots): Treat a missing input file the same way
+ as an input file with no usable data points. This is not the same
+ as skipping it cleanly as in the 2D case. 3D should be brought in line
+ with 2D, but it will require revision of the data structure handling.
+
+ * src/fit.c (fit_command): Give an error message if an input data file
+ is missing or not readable.
+
+ * src/graphics.c (do_plot): Re-indent code section dealing with
+ empty plots.
+
+2006-03-11 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/plot2d.c (cp_alloc) src/plot3d.c (sp_alloc): Our plot structures
+ have gained additional fields over the years, but not all of them were
+ being initialized on allocation. Switch to zeroing the entire structure
+ on allocation, then filling in the small number of non-zero fields.
+ Fixes rare segfault found while debugging "skip missing file" code due
+ to use of an uninitialized plot->p_count field.
+
+2006-03-10 Petr Mikulik <mikulik@physics.muni.cz>

+
+2006-03-06 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
+
+ * docs/titlepag.tex: The previous method of detecting pdflatex
+ vs. normal latex no longer works (some clever guys decided that
+ they should use pdflatex to make DVI files...). Give up trying to
+ sort out that mess. Just assume that hyperref knows this on its
+ own, these days.
+
+ * src/syscfg.h (OS): Provide a fallback definition to avoid using
+ an undefined macro.
+ (GP_EXCEPTION_NAME) [__WATCOMC__]: Define.

+2006-03-04 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ Support for 'with image' plots in Windows, from Bastian Maerkisch.

+ * term/win.trm (WIN_image): New function. An edited copy of
+ PM_image.
+ (TERM_ENTRY): Add entry for WIN_image.
+
+ * src/win/wgraph.c (GraphOp, GraphOpSize): Moved body of previous

+ GraphOp replaced by a call to the new function.
+ (drawgraph): Handle new opcode W_image.
+
+ * src/win/wgnuplib.h (W_image): New wgraph operation code.
+ (GraphOpSize): Added prototype.
+
+2006-03-04 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ Bastian Maerkisch's enhanced text mode patch for Windows:

+
+2006-03-04 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * config/makefile.cyg (HCWPATH): Look for HCW in the default place
+ where it installs itself.
+ ($(OBJS) $(WINOBJS) dbinary.$(O)): Make these depend on config.h.
+ (default, all): Generate config.h by real dependency.
+ (show.$(O)): Don't assume .o extension.

+
+2006-03-02 Mike Sutton <mws116@usa.com>

+
+2006-02-28 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/term.c (term_close_output): Fix fatal double-close error
+ triggered by error return from post.trm at any point where gppsfile

+
+ * term/post.trm: Fix broken linetype definitions loaded by
+ set term epslatex oldstyle
+
+2006-02-28 Lars Hecking <lhecking@users.sourceforge.net>
+
+ * demo/Makefile.am.in: Add *.pdb and *.r3d to EXTRA_DIST generation.
+
+ * docs/gnuplot.texi: Regenerated after recent documentation updates.
+
+2006-02-28 Per Persson <persquare@mac.com>
+
+ * term/aquaterm.trm: Added encoding support to aqua terminal. Currently
+ supports iso_latin_1, iso_latin2, and cp1250. Default is iso_latin_1.
+
+2006-02-27 Bastian Maerkisch <bmaerkisch@web.de>
+
+ SF patch [1436005] WIN: change sequence of pointstyles
+
+ * src/win/wgnuplib.h src/win/wgraph.c: Change the sequence of poinstyle

+ or gd.
+
+2006-02-26 Ethan A Merritt <merritt@u.washington.edu>
+
+ * demo/html/index.save: Update web site template for 4.1 demos.
+
+ * src/set.c(set_decimalsign) src/variable.c(locale_handler)
+ src/show.c(show_command show_decimalsign show_locale) docs/gnuplot.doc:
+ Work a little harder to show both the current input and output settings
+ for decimal point handling (LC_NUMERIC locale setting).
+
+2006-02-25 Ethan A Merritt <merritt@u.washington.edu>
+
+ * graph3d.c (do_3dplot): Contour lines are supposed to be in different
+ colors, but this was only working if the surface itself was drawn in a
+ simple linetype. Fix contour auto-coloring even for explicit rgb or
+ other surface-coloring modes.
+
+2006-02-25 Ethan A Merritt <merritt@u.washington.edu>
+
+ * src/gadgets.h src/term_api.h: Move line type definitions into
+ term_api.h, since they exist to request specific terminal behavior.
+ Remove definition of L_TYPE_NODRAW. It is now superseded by LT_NODRAW.
+
+ * src/misc.c (parse_colorspec); Now that LT_BACKGROUND is safe to pass
+ to all terminal drivers, allow it as a legal linetype (-3) in commands.
+
+2006-02-24 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * src/tables.c (set_palette_tbl pm3d_color_names_tbl): Support both

+
+2006-02-21 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * term/post.trm (PS_encode_image): The computation for the max number
+ of required bytes for encoding the image didn't take into account that
+ there is 8 bit alignment (potentially additional 7 bits) at the end
+ of each image line. The encoded image was written outside memory on
+ the heap and corrupted when cleared. Fixed, and added an assert()
+ test, after the fact, to compare encode size against memory size.
+
+2006-02-21 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * src/gplt_x11.c (scan_palette_from_buf): The read_input() status
+ was ignored and consequently when a partial read of the pipe happened
+ a full line was not removed from pipe. For long palettes garbage
+ remained in pipe when done and next command was bogus.
+
+ * src/gplt_x11.c (read_input_line): A new routine that will check
+ status of read_input and continue reading if only a partial read.
+ If there are too many reads, the routine gives warning.
+
+2006-02-21 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * src/getcolor.c (interpolate_color_from_gray): The index could go
+ to one past the end of the array and cause a program crash. This
+ was fixed with a bisecting routine as suggested by the old comment
+ nearby, as opposed to the linear search.
+
+2006-02-20 Ethan A Merritt <merritt@u.washington.edu>
+
+ * term/imagen.trm (IMAGEN_cvts): Obviously no one uses this driver,
+ because if they had they would have noticed that it's been trampling
+ on unallocated memory since version 3.7 times or earlier. Fixed.
+
+ * term/metapost.trm (MP_filled_polygon MP_boxfill): solid fill density
+ parameter was being interpreted incorrectly.

+
+2006-02-19 Dennis Linse <djlinse37@users.sourceforge.net>

+
+2006-02-19 Ethan A Merritt <merritt@u.washington.edu>
+
+ * term/gd.trm (image_do_crop): Move libgd version 2 dependency

+
+ * docs/Makefile.in: Add an empty target for "install-exec", and
+ remove gnuplot.info from the target "all". These changes are needed
+ in order for either a default "make" or "make install-exec" to
+ succeed on a system without emacs or makeinfo.
+ Bug #1430819.
+ Thanks to Dennis Linse <djlinse37@users.sourceforge.net>
+
+ Note: an alternative is not to use the .../missing script for
+ makeinfo, or somehow make the fact that it's missing a non-fatal
+ error.

+
+ SF patch [1432890] Win: rotated text at arbitrary angles

+
+2006-02-16 Bastian Maerkisch <bmaerkisch@web.de>
+
+ SF patch [1384525] Small fixes to gd terminals
+
+ * term/gd.trm: Fixes for Win32 to allow linking with bgd.dll or static.
+ - Static linking with gdlib is now possible (again) on windows (NONDLL
+ is taken into account).
+ - A new define GD_NEED_LOCAL_FONT_POINTERS is added. When defined
+ gd.trm will use local pointers to the fonts built into gdlib. This
+ is highly recommended by Mr. Boutell on Windows platforms. Currently
+ it is only activated on Windows when linking to bgd.dll.
+
+2006-02-12 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * term/post.trm (PS_encode_image PS_image): Bug fix for the PostScript
+ image using the five operand form (i.e., no palette). The bug was
+ that the max colors was not set to 2^N, where N is 1, 2, 4, 8, or 12.
+ So if the gray scale max was 128 (2^7) the brightness was lower than
+ it should have been.
+
+2006-02-12 Petr Mikulik <mikulik@physics.muni.cz>
+

+
+2006-02-11 Timothee Lecomte <timothee.lecomte@ens.fr>

+
+2006-02-02 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/gplt_x11.c (handle_selection_event): Clean up yesterday's
+ code a little, and separate the pixmap request from the mouse
+ coordinate string request. By making the string request
+ separately, it seems that klipper now notices it.
+
+2006-02-01 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/gplt_x11.c (handle_selection_event): Fix bad interaction
+ between gnuplot_x11 and X11 clipboard management tool "klipper".
+ Refuse to export the pixmap and colormap more than once per
+ plot export. For unknown reasons, klipper continues to ask for
+ copies of both ad infinitum. Fixes bugs ##1225866 and #1420675.
+
+2006-01-31 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/command.c: (VMS) replace MAILBOX with "PLOT$MAILBOX"
+
+ * src/set.c (set_timestamp): Use gp_strdup() rather than strdup().
+
+ * src/term_api.h: Remove trailing comma from definition of
+ t_termlayer.
+
+ * src/util.c (existdir): Special case VMS.
+
+ With these minor tweaks, the current gnuplot source will compile
+ and build under VMS using DECC. Not all drivers tested, though.
+
+2006-01-28 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/term.c (parse_term_size): New routine intended to be shared
+ by terminals with "set term <foo> size XX, YY" option. The routine
+ itself supports size specification in inches, cm, or pixels. The
+ calling terminal can limit which units are acceptable.
+
+ * term/post.trm (term_options): "set term ... size XX, YY" option.
+ This is intended to replace the older mechanism:
+ "set size ... ; set term ...". The new code gets the bounding box
+ right, which the old mechanism does not, and it rationalizes the use
+ of screen coordinates to match that of other (but not all) terminals.
+
+2006-01-26 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/datafile.c (df_read_matrix): Bugfix for "every" option in plot

+ not. Therefore test index against firstpoint before trying to parse
+ it as a number.
+
+2005-01-23 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * src/graphics.c (plot_image_or_update_axes): Fix for

+
+2006-01-21 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * src/graph3d.c (do_3dplot): The mistake of missing blank lines in a

+
+2006-01-19 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/color.c src/color.h src/gadgets.c src/gadgets.h: Move color_box

+ to generalize the placement options.

+ allows all the various point properties to be handled in hidden3d mode
+ except for variable pointsize. Variable pointsize is handled by adding

+
+2005-09-20 Ethan Merritt <merritt@u.washington.edu>

+ src/setc.c (set_tic_prop load_tic_user load_tic_series)
+ src/show.c (show_ticdef) src/unset.c (unset_tics) docs/gnuplot.doc:
+
+ Sourceforge patchset #1104018.
+ Allow both user-specified axis tics and auto-generated tics at the

+ * src/graphics.c (plot_image_or_update_axes): Use gp_alloc rather

+
+2005-09-16 Juergen Wieferink <wieferink@freenet.de>

+
+2005-09-15 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/term.c (write_multiline, on_page): New routine on_page(x,y) to
+ check coordinates for being in range of entire terminal drawing area.
+ Use this in write_multiline() to centralize text clipping (may extend
+ it to single line text later). Fixes bug #1274007 and a lot of old
+ complaints about segfaults in libpdf.
+
+ * src/term_api.h term/post.trm: But some terminals can clip text just
+ fine on their own, and do it more cleanly than on_page() can do. Define
+ a terminal flag TERM_CAN_CLIP for these cases, starting with post.trm.
+ If the flag is set for the current terminal, on_page() always returns
+ TRUE.
+
+ * src/graph3d.c (xtick_callback ytick_callback ztick_callback):
+ Since write_multiline() now does its own clipping, it does not need to
+ be wrapped by clip_put_text_just(). While we're here, apply text
+ rotation for tic labels.
+
+ * src/gadgets.c src/gadgets.h src/color.c: This leaves no callers for
+ clip_put_text_just(), so remove the routine altogether.

+
+ * demo/html/Makefile demo/html/index.save: Add rgb_variable.dem to the

+ This set of changes converts all users of struct label_struct to use
+ stucture text_label instead. This saves space everywhere, and
+ consolidates the label parsing and handling routines.
+
+ * docs/gnuplot.doc NEWS:

+
+ * src/gplt_x11.c: Do away with special (GC *)gc_pm3d; use the same gc

+
+ To switch back to the old behaviour compile with PM_OLD_ENHANCED_TEXT

+2005-07-27 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/set.c (set_timestamp) docs/gnuplot.doc:
+ Drag the "set timestamp" code into the modern era by accepting options
+ in any order. Add keyword "font" in front of the optional font string,
+ but for backwards compatibility do not require it. Update the
+ documentation to reflect current treatment of offset and font options.
+
+2005-07-26 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/set.c (set_xyzlabel): Check to see if next token is a valid
+ keyword before trying to parse it as a string. Fixes bug on, e.g.
+ 'set title offset 1,1'
+
+ * src/save.c (save_set_all): Write out keyword "offset" where
+ appropriate.
+
+2005-07-25 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/stdfn.c src/stdfn.h: Add a private function gp_strtod() in case
+ there are platforms that do not have a working strtod().
+
+ * src/datafile.c (df_tokenise): Use strtod(), via gp_strtod(),
+ to parse values read from a data file. On long input lines, this is
+ substantially faster than using sscanf(). The previous fast path
+ (non-Fortran) used atof() rather than strtod(), but that does not
+ give a status return or character length consumed.
+
+2005-07-25 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/pdf.trm (PDF_options PDF_linewidth): libpdf does not like zero
+ linewidth. Limit linewidths to 0.1 or greater.
+
+ * src/command.c (exit_command) docs/gnuplot.doc:
+ New command 'exit gnuplot' will unconditionally exit gnuplot immediately
+ even if invoked from within several nested layers of input stream. This
+ allows, for instance, binding a hotkey that can terminate gnuplot in
+ response to a keystroke in the plot window.
+
+2005-07-25 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/datafile.c src/datafile.h src/save.c src/set.c src/show.c
+ src/unset.c docs/gnuplot.doc:
+ New command 'set datafile fortran' to enable parsing of input files
+ containing Fortran D or Q floating constants. This was the default
+ until now, but it requires a second check of every value parsed,
+ which obviously slows down the input procedure. Now the second pass
+ is disabled by default, and only occurs if the fortran parsing option
+ is selected. Addresses complaints of slow input from large files.
+
+2005-07-23 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/command.c (print_command): Re-arrange code so that an expression
+ being printed is only evaluated once, rather than twice.
+ Fixes bug #1173508.
+
+2005-07-23 Harald Harders <h.harders@tu-bs.de>
+
+ * src/term.c (write_multiline): Use estimate_strlen rather than strlen.
+
+ * term/post.trm: Use a more foolproof method of estimating the width of
+ strings containing overprint characters.
+
+2005-07-22 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/parse.c (string_or_express): Remove unused variable.
+
+2005-07-22 Ethan Merritt <merritt@u.washington.edu>
+
+ Introduce a new terminal API routine (term->layer)(int layer). This
+ is used by the epslatex terminal (pslatex.trm) to handle the
+ "front" or "back" text attribute. In the future it might be used to
+ toggle other layering effects (transparency? contour levels?).
+
+ * src/term_api.h term/README: Define new entry point and a set of
+ layer names to pass into it.
+
+ * src/graph3d.c (do_3dplot) src/graphics.c (do_plot):
+ Call t->layer(TERM_LAYER_FRONTTEXT) and t->layer(TERM_LAYER_BACKTEXT)
+ at the relevant stages of plot generation.
+
+ * src/term.c (term_start_plot term_end_plot):
+ Call t->layer(TERM_LAYER_RESET) and t->layer(TERM_LAYER_END_TEXT)
+ at start and end of each plot, respectively.
+
+ * term/pslatex.trm: Implement EPSLATEX_layer() mechanism.
+
+2005-07-20 Juergen Wieferink <wieferink@freenet.de>
+
+ * src/parse.c (string_or_express): Do not call int_error() for invalid
+ expressions. Fixes "(s)plot 1/0".
+
+2005-07-19 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/cgm.trm: Add a warning that Win2000 cannot handle filled
+ polygons with more than 50 vertices. Not our fault! Bug #955074.
+
+2005-07-18 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/datafile.c (df_parse_string_field): Fix tab-containing string
+ constant which was broken when indent replaced tabs with spaces.
+
+ * configure.in src/term.h term/post.h term/post.trm term/pslatex.trm:
+ Repair the ordering of configuration options for building the post,
+ epslatex, and pslatex terminals. This selection is now made at the top
+ of term.h, as is selection of the enhanced text stringlength estimation
+ pseudo-terminal.
+
+2005-07-16 Juergen Wieferink <wieferink@freenet.de>
+
+ * src/command.c (load_command): Issue an error message if any
+ tokens or further commands follow a "load <file>" command.
+ Sourceforge patch #1210835.
+
+2005-07-16 Ethan Merritt <merritt@u.washington.edu>
+
+ * demo/stringvar.dem: Add a demo showing a plot command that
+ generates datafile names via a string-valued function, now possible
+ because of the new string_or_expression code.
+
+2005-07-16 Juergen Wieferink <wieferink@freenet.de>
+
+ Allow a single plot or splot command to contain a mixture of
+ functions, e.g. sin(x), and constant expressions including
+ string-valued constant expressions, e.g. sprintf("file.%d",n).
+
+ * src/datafile.c (df_open) src/datafile.h src/plot2d.c
+ src/plot3d.c src/fit.c src/set.c:
+ Parse filename from plot/splot/fit command before calling df_open(),
+ and pass the resulting string to df_open() as a new argument.
+
+ * src/parse.c (string_or_expression) src/parse.h:
+ New function that can safely parse either a constant expression
+ or a dummy function. string_or_expression() will return a pointer
+ to a string if it successfully parsed a string-valued expression.
+ It will return a pointer to an action table if it successfully
+ parsed a dummy function. If it parsed a non-string expression, both
+ the string pointer and the action table pointer will be NULL.
+
+ * src/eval.c (imag):
+ The use of string_or_expression() by splot/plot/fit allows one to
+ mix string-valued functions and "true" functions in the same command.
+ However, a string-valued function containing what looks like a dummy
+ variable (normally x or y) is not parsed correctly. This error is
+ eventually discovered and reported in imag().
+
+2005-07-16 John Bollinger <bbands@yahoo.com>
+
+ * demo/finance.dem demo/finance.dat: New demo illustrating
+ various gnuplot features applied to display of financial data.
+
+2005-07-15 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * src/term.c (enhanced_recursion) [POSTSCRIPT_DRIVER]: added
+ a conditional to allow builds without PostScript/pslatex drivers
+ again.
+
+ * term/pslatex.trm (PSLATEX_DRIVER): Define this macro here, where
+ it belongs.
+
+ * term/post.trm (POSTSCRIPT_DRIVER): Likewise.
+
+ * term/post.h: Remove #define PSLATEX_DRIVER --- it had no
+ business sitting in here.
+
+ * src/term_api.h (PC_setup) [PC]: Add missing prototype.
+
+ * src/gadgets.c: Add missing #include "graph3d.h".
+
+ * src/datafile.c: Re-indented almost the entire file. Was
+ violating CodeStyle all over the place.
+
+ * src/term.h [DJGPP, DJSVGA]: Allow build without GRX (by setting
+ DJSVGA to zero).
+
+ * config/makefile.dj2 (EXENAME): Removed version number from name.
+ (TERMFLAGS): DJSVGA definition moved to front, explain that
+ setting this to zero has a different effect now.
+ (TERMLIBS): Renamed to usual name (was LDFLAGS).
+ (CFLAGS): Updated to support build of current source.
+ (LINKOPT): Removed entry for GRX library.
+
+ * src/breaders.h: Added missing HAVE_CONFIG_H conditional.
+
+2005-07-14 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/internal.c src/term.c src/gplt_x11.c term/gd.trm: Fix mangled use
+ of FPRINTF debugging macro.
+
+ * term/README term/gd.trm: Clarify documentation of term->suspend and
+ term->resume. Remove TERM_CAN_MULTIPLOT flag from gd.trm, since it has
+ no suspend/resume entry points.
+
+2005-07-13 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/command.c (do_system_func): Fix incorrect placement of final
+ return code outside of the main conditional code segment.
+ Fixes compilation error under mingw reported by Dietmar Warning.
+
+ * src/graph3d.c (do_3dplot) src/graphics.c (do_plot)
+ src/term.c (test_term) term/post.trm term/pslatex.trm:
+ Remove all epslatex-specific code from the gnuplot core routines.
+ It was not working anyhow. This reverts the epslatex driver to
+ the old behaviour of ignoring any distinction between "front" and
+ "back" text labels. It also clears the deck for a different
+ approach that adds a terminal API routine to handle this sort of
+ terminal-specific requirement (SourceForge patchset #1191202).
+
+2005-07-11 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/breaders.h src/datafile.c src/datafile.h src/fit.c src/plot2d.c
+ src/plot3d.c src/set.c: Simplify conditional compilation controlled by
+ --enable-binary-data-file. Instead of having a different number of
+ parameters to df_readline() and plot_option_binary(), expost a uniform
+ definition but add an auxilliary routine df_set_plot_mode() in the
+ BINARY_DATA_FILE case. Also clean up the general coding style and remove
+ redundant structure definitions. This prepares for easier implementation
+ of Juergen Wieferink's "plot string or expression" patch.
+
+2005-07-10 Harald Harders <h.harders@tu-bs.de>
+
+ * docs/psdoc/ps_symbols.gpi: Spiffed up sample page for PostScript
+ symbols and linetypes.
+
+2005-07-10 Shigeharu Takeno <shige@iee.niit.ac.jp>
+
+ * docs/gnuplot.doc: Fix typos.
+
+2005-07-10 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/command.c src/graph3d.c src/graphics.c src/term.c:
+ Whitespace cleanup.
+
+ * src/internal.c (f_gprintf): Use dynamic allocation for output buffer.
+
+2005-07-10 Juergen Wieferink <wieferink@freenet.de>
+
+ * src/command.c (do_system_func) src/command.h src/eval.c
+ src/internal.c (f_system) src/internal.h src/scanner.c (substitute):
+ New built-in string function system("command") which executes a shell
+ command and returns the resulting output stream as a string variable.
+ Consolidate this code with existing shell escape code (backticks) via
+ a new routine do_system_func().
+
+ * docs/gnuplot.doc: Document new system("command") function.
+
+2005-07-09 Juergen Wieferink <wieferink@freenet.de>
+
+ * src/eval.c src/eval.h src/parse.c src/parse.h: Consolidate code
+ in add_udv() and add_udv_by_name(). Move add_udv_by_name() from parse.c
+ to eval.c so that lower level routines in internal.c and eval.c do not
+ have to include parse.h.
+
+2005-07-08 Juergen Wieferink <wieferink@freenet.de>
+
+ * src/internal.c (f_call f_calln): Free all strings used as dummy
+ variables; fixes memory leak.
+
+ * src/eval.h src/eval.c: New function free_at() that frees all strings
+ stored in an old action table so that there is no memory leak when the
+ table is re-used.
+
+ * src/command.c (define): Free old action table if a function is
+ redefined; fixes memory leak.
+
+ * src/parse.c (temp_at parse_primary_expression): Recode to use new
+ free_at() routine.
+
+2005-07-08 Ethan Merritt <merritt@u.washington.edu>
+
+ * docs/gnuplot.doc src/internal.c (f_range f_strstrt)
+ src/parse.c (parse_primary_expression):
+
+ Switch convention of substring indexing from C-like (first character has
+ index 0) to Fortran-like (first character has index 1). This makes the
+ routines strstrt() and word() consistent with each other, and makes the
+ range specifier form string[beg:end] consistent with both of them.
+
+ * demo/stringvar.dem: Expand demo to illustrate use of the substring
+ operator and the various string string functions.
+
+2005-07-07 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/gp_types.h: Provide a pseudo-plot type NODATA to indicate that
+ this plot is being skipped because the datafile was empty.
+
+ * src/plot2d.c (eval_plots): When no valid points are found in a data
+ file, issue a warning message, mark the current plot as NODATA, but then
+ process the rest of the command line as normal rather than bailing to
+ command line. This is a return to the behavior of 3.7.2, except that now
+ there is an explicit warning message for each empty file. If other code
+ sections code are sensitive to lack of data, they can test for NODATA.
+ Addresses enhancement requests #1063873 and #1204125.
+
+2005-07-06 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/internal.c (f_sprintf): Switch from using a fixed length output
+ buffer to a dynamically-allocated one. The string output by sprintf is
+ no longer limited to 80 characters.
+
+ * demo/stringvar.dem: Test dynamic extension of sprintf output buffer.
+
+ * src/datafile.c (df_readline): Only call add_key_entry() if the current
+ plot is really a histogram; otherwise specifying 'using key(<n>)'
+ causes a segfault on non-histogram plots.
+
+ * docs/gnuplot.doc: Clarify the method of auto-generating key titles
+ and tic labels for columnstacked histogram style.
+
+2005-07-03 Juergen Wieferink <wieferink@freenet.de>
+
+ * src/command.c (system_command): Simplify code by using
+ try_to_get_string() to extract the command string from input line.
+
+ * docs/gnuplot.doc: Fix typo in the documentation for words(string).
+ Add mention that `set style fill` applies to filledcurves.
+
+2005-07-03 James R. Van Zandt <jrv@debian.org>
+
+ * term/gd.trm: Document "set output '| display png:-'".
+
+2005-07-02 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/eval.c src/internal.c src/internal.h src/parse.c:
+ New string-related functions:
+ + words("string") returns the number of whitespace-separated words in
+ the string. For example, words("A B C D") = 4
+ + word("string",N) returns the Nth word in the string. For example,
+ word("A B C D",3) = "C"
+
+ * docs/gnuplot.doc: Document new functions word() and words().
+
+2005-06-29 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/util.c src/util.h: #define isstringvalue(c_token) to include both

+
+ * src/plot2d.c src/plot3d.c src/set.c term/emf.trm term/gd.trm
+ term/post.trm term/tgif.trm term/x11.trm: Modify all callers of
+ isstring+isstringvar to either use the new combined routine or to call
+ try_to_get_string() directly and handle both string and non-string
+ returns.
+
+ * src/axis.h: And one caller was hiding in a macro.
+
+ Fixes the following bugs:
+ + `plot func(x), FILENAME` gave an error
+ + `set term pslatex font FONTNAME` should not have been legal
+ + `set title "foo" -1,-1` (old style syntax with no "offset" keyword)
+ caused a parsing error
+ + fixes order-dependence of options to `set term emf`
+
+ There are 60 odd instances of isstring() remaining, many of which are
+ tests for format strings (e.g. `set format xy "format_string"`).
+
+2005-06-28 Ethan Merritt <merritt@u.washington.edu>
+
+ * docs/checkdoc.c: Allow for lines beginning with '=' in gnuplot.doc
+ (now used to indicated an explicit index entry).
+
+2005-06-27 Shigeharu Takeno <shige@iee.niit.ac.jp>
+
+ * src/set.c (parse_label_options): Allow string variable or expression

+
+2005-06-27 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/internal.c (f_calln): Prevent buffer overflow if more parameters
+ than expected are passed to a function.
+
+2005-06-26 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * docs/Makefile.in: Replace "sort" by "LC_ALL=C sort" when building
+ allterm.h to avoid localized sorting.
+
+2005-06-24 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * docs/gnuplot.doc: Rewritten section for "help exit".
+
+2005-06-22 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/eval.c src/internal.h src/internal.c (f_strstrt): New built-in
+ string function that searches for a substring within a longer string.
+ Equivalent to C library function strstr(haystack,needle) except that
+ rather than returning a pointer, it returns an index. Example:
+ n = strstrt("haystaneedleck","needle")
+ sets n to 6.
+
+ * demo/stringvar.dem docs/gnuplot.doc: Document and add to string demo.
+
+ * NEWS: Update list of new features.
+
+2005-06-20 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/set.c (set_xyzlabel): Allow string variable or expression for
+ font name. This is a variant of a patch from Shigeharu TAKENO.
+
+ * src/plot2d.c (get_data histogram_range_fiddling): Clean up histogram
+ code dealing with missing data or blank lines. Fixes an autoscaling bug
+ if a data file ends with blank lines.
+
+2005-06-19 Ethan Merritt <merritt@u.washington.edu>
+
+ * docs/gnuplot.doc src src/set.c (set_decimalsign): New command option
+ `set decimalsign {locale {"locale_spec"}}`
+ takes the decimal sign character from the locale specified for the
+ locale "locale_spec" or from the locale specified in the enviromental
+ variables LC_NUMERIC, LC_ALL, or LANG.
+
+ * src/save.c (save_set_all): Save the current locale for LC_NUMERIC
+ as well as the actual current value of decimalsign.
+
+ * src/show.c (num_to_str) src/util.c (gprintf): Allow for the
+ possibility that the current decimal sign is a comma rather than a dot.
+
+ * src/variable.c (locale_handler): Expand output by `show locale` to
+ show the current values of LC_NUMERIC LC_CTYPE and LC_TIME.
+
+ * src/unset.c (unset_decimalsign): If the decimalsign is reset using
+ `unset decimalsign`, then set the internal locale to C.
+
+2005-06-18 Harald Harders <h.harders@tu-bs.de>

+
+2005-01-15 Bastian Maerkisch <bmaerkisch@web.de>
+
+ * term/pm.trm src/os2/gclient.c src/os/pm_msgs.h: Move definition of

+
+ * term/pm.trm (PM_set_font): Fix font selection for pm terminal in case

+
+ * src/plot.c (RexxInterface): Replace input_line[] by gp_input_line[]
+ in code sections which are only compiled on OS/2.
+
+ * src/os2/gclient.c (ParseText): Fix super- and subscripts in enhanced
+ mode of the pm terminal.
+
+2005-06-14 Ethan Merritt <merritt@u.washington.edu>
+
+ New functions related to string variables:
+ sub = "ABCDEF"[beg:end]

+
+ * src/parse.c (parse_primary_expression): Check for a postfixed
+ range specifier at the end of parsing an expression.
+
+ * src/internal.c (f_range) src/internal.h: New internal function
+ f_range() that applies a range specifier to a string in order to

+
+ * src/eval.c src/eval.h: Define an index code for the internal

+
+ * demo/stringvar.dem demo/all.dem docs/gnuplot.doc:
+ Document and provide examples of substring syntax.
+ Add string variable demo to all.dem
+
+2005-06-13 Frank Maas / Ethan Merritt
+
+ * docs/gnuplot.doc: Clarify histogram documentation to explain that

+
+2005-06-13 KITA Toshihiro <t-kita@cc.kumamoto-u.ac.jp>
+
+ * docs/gnuplot.doc: Update `set xlabel` example to use the `offset`

+
+2005-06-04 Juergen Wieferink <wieferink@freenet.de>
+
+ * src/parse.c eval.c eval.h internal.c command.c set.c:
+ Code clean up: replace explicit test-and-free of string values with a

+
+2005-06-04 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/eval.c src/eval.h src/show.c src/setshow.h: Move the routine
+ disp_value() and its helper num_to_str() from eval.c to show.c. This
+ reduces the need for mutual cross-referenced #includes, and anyway the
+ routine belongs in either show.c or save.c because that's what it does.
+
+2005-06-04 Juergen Wieferink <wieferink@freenet.de>
+
+ * src/show.c (disp_value) src/setshow.h: Introduce an additional
+ parameter to disp_value() that controls whether or not quotes are

+ code at all call sites.
+
+ * src/command.c (print_command) src/internal.c (DEBUG code only)
+ save.c (save_variables__sum) show.c (disp_at show_variables):
+ Modify call sites of disp_value() to explicitly request quoted strings
+ if necessary.
+
+2005-06-02 Ethan Merritt <merritt@u.washington.edu>
+
+ * docs/README docs/titlepag.tex docs/doc2tex.c docs/doc2texi.el:
+
+ Add a mechanism to auto-generate an index for the documentation via the
+ TeX package "makeindex". All TeX-derived documentation formats will
+ include the index. Juergen Wieferink has similarly modified the
+ generation of gnuplot.info. A keyword is inserted in the index if
+ it is found on a line of gnuplot.doc beginning with with '?' or '=',
+ or if it appears as the final word of a phrase wrapped in backtics.
+ This latter rule picks up cross-reference sites, but may be disabled
+ by compiling doc2tex with -DNO_CROSSREFS.
+
+ * docs/doc2.gih.c docs/doc2hlp.c docs/doc2ipf.c docs/doc2ms.c docs/doc2rnh.c
+ docs/doc2rtf.c: Ignore leading '=' character in input stream. These
+ conversion tools do not know how to generate an index.
+
+ * docs/gnuplot.doc term/gd.trm term/x11.trm: Add some explicit indexing
+ entries (keywords with a '=' in the first column of the line).
+
+ * docs/Makefile.in: Switch generation of html documentation to use
+ latex2html toolchain rather than going via gnuplot.texi
+
+2005-06-02 Juergen Wieferink <wieferink@freenet.de>
+
+ * src/eval.c (Gstring gpfree_string) src/eval.h: Separate the freeing

+
+ * src/gplt_x11.c: Lots of coding style changes, mainly missing

+
+ SF Patch [1117060] Mod to post.trm for PostScript Level 1 images.
+
+ * term/post.trm: New routine PS_encode_image(), new postscript variable
+ InterpretLevel1 and some other changes.

+2005-05-24 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/tables.c: Allow shorthand for "set macros".

+
+ * src/term.c (term_init): As per discussion on gnuplot-beta, when
+ changing to a new terminal type, check flags for TERM_NO_OUTPUTFILE
+ associated with the new type. If present, then close current output
+ file cleanly rather than reopening and overwriting it.
+ Fixes bug #1182499.

+
+ * term/gd.trm term/mif.trm term/pdf.trm: Code cleanup - remove static

+ * term/gd.trm (PNG_options): Accept string variable for font name.
+
+ * src/plot2d.c (get_data eval_plots): If the x-axis is in log mode,

+ when the plot style is histograms.

+ Add new TBOOLEAN allwindows to the bind_t structure.
+ New routine bind_all() sets this flag from "bind all <foo> <baz>".

+2005-03-17 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * src/graph3d.c (do_3dplot): Fix 'set pm3d at X; splot...with pm3d at Y'

+
+ * src/graph3d.c (plot3d_points_pm3d plot3d_points): Remove routine
+ plot3d_points_pm3d, and handle pm3d-colored points in plot3d_points
+ instead. This removes any special drawing order for the points.
+
+2005-03-16 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * src/axis.h (AXIS_ACTUAL_MAX, AXIS_ACTUAL_MIN): New macros to

+ up the internal status.
+
+ * src/util3d.c (IN_AXIS_RANGE): New macro, equivalent to calling
+ inrange() with the two endpoints of any given axis' range. Makes
+ code a bit more readable.
+ (edge3d_intersect): New local macros INTERSECT_PLANE,
+ INTERSECT_DIAG to centralize lots of very similar code blocks.
+ Implement fix for clipping of -VERYLARGE points in the presence of

+ (two_edge3d_intersect): Use new macro IN_AXIS_RANGE, reindent, for
+ readability.

+ * term/emf.trm term/gd.trm term/pdf.trm term/pm.trm term/post.trm
+ term/svg.trm term/x11.trm src/gplt_x11.c src/gplt_x11.h:
+ Modify term->set_color() to handle colorspec type LC_LT.
+ This has the effect of changing the current line color to that of
+ default linetype <lc> without changing any other line properties.
+
+ * misc.c (lp_parse) save.c (save_set_all) show.c (show_linestyle)
+ docs/gnuplot.doc:
+ Allow line color {linecolor|lc} to be specified separately from the
+ linetype. For example, this command will give a dashed black line:
+ set style line 1 lt 2 lc -1
+ and the following will give a dashed gold line:
+ plot sin(x) with lines lt 2 lc rgb "gold"
+
+ * demo/dashcolor.dem: Demo of choosing both linetype (dot/dash pattern)

+
+ * src/misc.c (arrow_parse): Bugfix: Keep current linetype as the default

+ N Matsuda (Tokyo Denki University).
+
+2005-03-04 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/datafile.c: Introduce a defined constant MAX_TOKEN_LENGTH
+ rather than trusting multiple call sites to declare consistently
+ sized character arrays.
+
+ * src/eval.c src/datafile.h src/datafile.c docs/gnuplot.doc:
+ New internal function f_stringcolumn() usable only inside a "using"
+ specification; pushes the content of a data column onto the evaluation
+ stack as a string variable.
+ Syntax:
+ plot 'foo' using (stringcolumn(1) eq "baz" ? column(2) : column(3))
+
+ * src/datafile.c (df_readline df_3dmatrix df_readbinary):
+ Set a flag to indicate that we are in the process of evaluating a
+ "using" specification.
+
+ * src/datafile.c (f_column f_timecolumn f_stringcolumn):
+ Report an error if any of the <xxx>column() functions are called
+ outside the context of a "using" specification.
+
+ * configure.in: Remove the "EXPERIMENTAL" warning from the histogram
+ and datastrings options; they've had 2 years of testing.
+
+2005-03-02 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/unset.c (unset_historysize): Rearrange #ifdefs for GNUPLOT_HISTORY
+ to prevent compiler warnings about unused function definitions.
+
+ * src/term.h term/post.h term/post.trm: Introduce a statement
+ '#define PSLATEX_DRIVER' into post.h that controls whether or not the
+ pslatex/epslatex terminal code is built. Add #ifdef PSLATEX_DRIVER
+ in appropriate places. Without this it was impossible to build gnuplot
+ with post.trm but not pslatex.trm.
+
+ * src/term.h: Remove aed.trm and tek.trm from SHORT_TERMLIST set of
+ terminals, but add estimate.trm if it is enabled.
+
+ * configure.in src/graphics.c src/plot2d.c src/save.c src/set.c

+
+2005-02-26 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/pm3d.c (set_plot_with_palette): Don't trigger display of the
+ colorbox in 2D plots just because an explicit line color was set.
+
+ * misc.c (parse_fillstyle): accept full keyword "fillstyle" in addition
+ to short form "fs".
+
+2005-02-24 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/graphics.c(plot_c_bars) src/plot2d.c(eval_plots) docs/gnuplot.doc:
+ New keyword '... with candlesticks {whiskerbars}' that draws horizontal
+ crossbars at the top and bottom of the whiskers. This is typical for
+ box-and-whisker plots. The new keyword is in lieu of adding a
+ separate "boxplots" plot style (patch #624000).
+
+ * src/gplt_x11.c (pr_fastrotate) term/x11.trm (documentation):
+ The fully general implementation of text rotation added in version 4.0
+ is *much* slower than it used to be. This patch adds a new X resource
+ gnuplot*fastrotate: {on|off} that reverts to the faster but imperfect
+ rotation method. The default is "on", which favors fast rendering at
+ the cost of possibly corrupting colors of nearby plot elements.
+
+2005-02-22 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/x11.trm: Fix botched optimization in previous patch.
+
+2005-02-21 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/x11.trm: Implement solid fill rectangles and polygons as a
+ true solid color, with variable fading toward background color, rather
+ than approximating by a set of 3 half-tone patterns.
+
+ * docs/gnuplot.doc: Explain that for some terminals the size of a "dot"
+ can be changed using linewidth.
+
+2005-02-18 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/pdf.trm: Allow "lw" as an abbreviation for "linewidth"
+ * term/post.trm: Make dash styles 6 and 7 a bit more distinctive
+ * term/emf.trm: Add option 'set term emf {linewidth <factor>}'
+ * term/gd.trm: Solid fill with density < 1 was not working with
+ rgb colors. Trivial fix.
+ * term/gd.trm: Add option 'set term ... {linewidth <factor>}';
+ increase maximum linewidth from 6 to 12
+
+ * src/graphics.c (boundary): When estimating the length and height
+ of xlabel, increase the number of lines by one if we're in enhanced text
+ mode and there seems to be a subscript. This test can be fooled if the
+ label has disabled enhanced text processing.
+
+2005-02-18 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * src/command.c src/tables.c src/set.c src/unset.c docs/gnuplot.doc: Let

+ descriptive error if gnuplot has not been configured with GNU readline.
+
+2005-02-17 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/pdf.trm: Add terminal options for monochrome and for dashed
+ lines:
+ set term pdf {mono|color|colour} {solid|dashed {dl dashlength}}
+
+ The defaults remain the same as before (color solid). The monochrome
+ option only affects linetypes; you can still use color explicitly
+ in filled areas or by using rgb specifications for line styles.
+
+ * configure.in: Check for dashed line support in pdflib.
+
+2005-02-16 Harald Harders <h.harders@tu-bs.de>

+ Call shared routines rather than duplicate code in-line.
+
+2005-02-14 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/pdf.trm (PDF_options PDF_init PDF_dot): Add terminal option
+ {rounded|butt} exactly parallel to post.trm. The default is butt

+ rounded joins.
+
+2005-02-14 Petr Mikulik <mikulik@physics.muni.cz>

+2005-02-14 Harald Harders <h.harders@tu-bs.de>
+
+ * term/pslatex.trm: SourceForge patch #1121972 "Improve input encoding

+
+ * src/gplt_x11.c: All calls to x11 font handling routines are
+ conditionally substituted by the equivalent calls to multi-byte
+ routines if --enable-x11-mbfonts is configured, and a multi-byte
+ font has in fact been selected.
+
+ * NEWS term/x11.trm: Add documentation that describes the specification

+ set term x11 font "mbfont:<primary font>;<secondary font>"
+ set label "foo" font "mbfont:<primary font>;<secondary font>"
+
+2005-02-10 Ethan Merritt <merritt@u.washington.edu>

+ * docs/gnuplot.doc src/set.c (set_xyzlabel) src/save.c (save_set_all)
+ src/show.c (show_xyzlabel): New suboption `set ... {{no}enhanced}` for
+ plot title and axis labels, analogous to the noenhanced option for the
+ plot key entries. This allows, for example, using a filename with
+ underscores as part of the plot title.
+
+ * src/graphics.c (do_plot) src/graph3d (do_3dplot): Disable enhanced
+ text processing while writing out plot title or axis label text if the
+ noenhanced flag is set in the corresponding label_struct.
+
+ * docs/gnuplot.doc: Correct the documentation to say
+ 'set multiplot layout <rows>,<cols>' (rows/cols were reversed in the
+ previous version, and mis-described in the example).
+
+2005-01-04 Bastian Maerkisch <bmaerkisch@web.de>
+
+ * src/os2/gclient.c: Contains my attempt to implement pattern filling
+ for the pm terminal. I gave this a bit of testing, but I have to admit
+ that the result looks ugly together with the widelines option. But
+ here you go anyway as 'widelines' has to be improved later anyway. It
+ should work fine without 'widelines'...
+
+ * src/os2/gnupmdrv.c: Newer versions of gcc on OS/2 no longer have
+ fcloseall(), but _fcloseall().
+
+ * src/os2/gclient.c src/os2/dialogs.c src/os2/print.c: Clean up by
+ removing some unused variables and code (some put into #if 0/#endif);
+ some minor changes to layout - this basically removes anoying warning
+ messages during compilation.
+
+2004-12-31 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/estimate.trm src/term.h: New pseudo-terminal driver whose sole
+ function is to parse a string in enhanced text mode and return the
+ number of character-widths in the resulting output text.
+
+ * configure.in NEWS src/term_api.h src/term.c (estimate_strlen):
+ New routine estimate_strlen(char *text). Its default behaviour is to
+ return strlen(text). But if the currently active terminal is in
+ enhanced text mode, and the current plotting context does not disable
+ enhanced text, then instead it calls the estimate.trm pseudo-terminal
+ term->put_text(text) in order to determine the approximate width of
+ the eventual output string. This feature may be disabled using
+ ./configure --disable-strlen_estimation
+
+ * src/graph3d.c src/graphics.c: Where strlen(text) is used to reserve
+ space on the plot (e.g. leaving room for tic labels or key box entries)
+ call the new routine estimate_strlen(text) instead. This allows more
+ accurate plot layout in enhanced text mode. The improvement is
+ particularly noticible if the y-axis tic format uses enhanced text mode.
+
+ * term/x11.trm (X11_options ENHX11_put_text): Try harder to determine
+ what the default fontsize is so that string lengths can be estimated.
+
+2004-12-30 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/term_api.h term/README: Add a new terminal flag bit
+ TERM_ENHANCED_TEXT that is set whenever the terminal is currently
+ operating in enhanced text mode. The will allow improved estimation of
+ text string length by the core code.
+
+ * aquaterm.term dumb.trm gd.trm pdf.trm pm.trm post.trm svg.trm x11.trm:
+ Set or clear TERM_ENHANCED_TEXT flag in term->options() code
+ that parses the "{no}enhanced" terminal option.
+
+2004-12-29 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/mouse.c (MKSTR): Do not allow embedded newlines in the format
+ used for tracking mouse motion via an extra status line at the bottom

+
+2004-12-23 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/ggi.trm (GGI_fillbox GGI_set_color): Implement color selection

+
+2004-12-22 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/mouse.c: Remove unused routine event_print().

+
+ * term/fig.trm (FIG_put_text) term/gd.trm (PNG_put_text, ENHGD_FLUSH):

+
+2004-12-20 Bastian Maerkisch <bmaerkisch@web.de>
+
+ * term/pm.trm (PM_set_color): Reflect recent changes of parameters in
+ term entries.
+
+ * src/os2/gnupmdrv.h src/os2/gclient.c: gnupmdrv.c and gclient.c both
+ used to define variable bWidelLines, but it should be the same one.
+ This patch adds an 'external' declaration in gnupmdrv.h, and removes
+ the definition from gclient.c.
+
+ * src/os2/gclient.c: Within GnuplotPM "Options->Gnuplot docs...", it
+ did not open gnuplot.inf when using NewView, a widely used view.exe
+ replacement. Replaced the fixed sized buffer solution with code using
+ a dynamic buffer.
+
+ * src/os2/gclient.c: This fixes text rotation for the pm terminal. The
+ variable bHorz, which used to indicate horizontal text, has now been
+ removed completely. Now pm terminal behaves similar to the postscript
+ terminal.
+
+2004-12-15 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>

+2004-12-07 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/emf.trm: Implement term->set_color(), term->filled_polygon,

+
+2004-12-07 Petr Mikulik <mikulik@physics.muni.cz>

+
+ Run valgrind to find memory leaks.
+
+ * term/x11.trm (X11_make_palette): Free palette gradient after sending

+
+ * src/set.c (set_cntrparam): Free old dynamic contour level array before

+
+ * src/set.c (set_xyzlabel): Free dynamic label string after copying it

+
+ * src/parse.c (temp_at): Add a garbage-collection step to the

+
+ * src/set.c (set_palette): Fix bug #1077699 - parser was skipping

+
+2004-12-03 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+

+
+2004-12-02 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/gd.trm: Keep track of current rgb values in parallel to the

+
+ * term/x11.trm: Add missing X resource to the table in the docs.
+
+ * configure.in: Remove obsolete messages relating to old png driver.
+
+2004-12-01 Ethan Merritt <merritt@u.washington.edu>
+
+ Add colorspec to linetype, and hence to all 2D and 3D plot elements.
+ These changes all depend on configuration with --enable-pm3d
+ Add support and demo example of using explicit RGB colors or gnuplot's
+ internal pre-defined color names:
+ set style line 1 lt rgbcolor "violet" lw 2
+ set style line 2 lt rgbcolor "#FFA080" lw 2 # salmon pink
+
+ * src/term_api.h:
+ Add new field "struct t_colorspec pm3d_color" to lp_style_type, so that
+ any plot element with an associated line type can use palette-based or
+ RGB colors.
+
+ * src/term.c (term_apply_lp_properties):
+ Check lp_style_type.use_palette flag, and if set apply the colorspec
+ rather than a simple linetype color.
+
+ * src/misc.c (lp_parse parse_colorspec):
+ Call parse_colorspec() as part of normal line type parsing. This allows
+ "lt {rgbcolor 'name'} | {palette {cb <val> | frac <val> | z}}" anywhere
+ that "lt <val>" is currently valid.
+
+ * src/graphics.c (do_plot plot_boxes plot_c_bars do_key_sample):
+ Everywhere that we would normally call t->linetype(), check use_palette
+ and instead call apply_pm3dcolor()
+ Everywhere that we would normally call t->fillbox(), check use_palette
+ and instead call t->filled_polygon() via new routine fill_corners()
+
+ * src/plot2d.c (eval_plots): Do not allow "lt palette z" in 2D plots
+
+ * src/save.c src/show.c:
+ save/show colorspec options associated with line styles and text colors
+
+ * src/set.c:
+ Allow text color to use full colorspec options.
+
+ * src/tables.c src/tables.h: New function reverse_table_lookup() that
+ returns the keyword associated with a table value; this is used to look
+ up the colorname associated with an RGB value.
+
+ * NEWS docs/gnuplot.doc: Document new functionality and syntax.
+
+ * demo/colorwheel.dem:
+ Set palette mode to standard HSV color wheel and define common colors as
+ macros. Allows terminal-independent commands such as
+ plot sin(x) with lines @orange
+
+ * demo/rainbow.dem:
+ Demonstrate two approaches to defining terminal-independent colors for
+ plot elements. (1) Load 'colorwheel.dem' to create a palette from which
+ colors can be selected. (2) Use the new colorspec type RGB to request
+ specific named colors, as in
+ set style line 1 lt rgbcolor "sea-green"
+ This only works well on terminals that support full RGB color modes.
+ Some palette-based terminals will approximate the requested color using
+ whatever palette color is closest, but the results may not be pleasing.
+
+2004-12-01 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/plot2d.c (eval_plots) src/plot3d.c (eval_3dplots): Add
+ END_OF_COMMAND check before trying to parse possible backwards

+
+2004-11-27 Ethan Merritt <merritt@u.washington.edu>
+
+ * docs/gnuplot.doc docs/gnuplot.texi: Re-format a large section of text
+ dealing with binary files. The previous layout caused PDF output to
+ treat the whole section as quoted monospace text, as for a code example.
+
+2004-11-27 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/color.h: Add new colorspec type TC_RGB, allowing colors to
+ be specified as an RGB triple stored as (RR<<16)+(GG<<8)+BB with
+ red, green, and blue components running from 0 - 255.
+
+ * src/gadgets.c (apply_pm3dcolor) src/gadgets.h: Pass RGB color
+ specifications to terminals via the new API for term->set_color().
+
+ * src/gplt_x11.c src/gplt_x11.h term/*.trm (set_color):
+ Implement set color to specified RGB triple in these terminals

+
+2004-11-26 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/term_api.h term/README: Change from term->set_color(double gray)
+ to term->set_color(struct t_colorspec *colorspec). This sets the stage
+ for allowing color specification mechanisms other than a PM3D palette.
+ The immediate intent is to allow direct requests for RGB color values.
+
+ * term/*.trm: Convert all terminal types providing set_color() to the
+ new API. No change in terminal behavior or capabilities.
+ Terminals affected:
+ aquaterm cgm fig gd metapost pdf post pslatex svg
+ tgif vgagl win x11 pstricks
+
+ * src/color.c (set_color): This is the only routine that calls

+ palette gray value.
+
+2004-11-25 Ethan Merritt <merritt@u.washington.edu>
+

+
+2004-11-24 Ethan Merritt <merritt@u.washington.edu>
+
+ src/gplt_x11.c: Set background color for pattern-fill explicitly each

+ to be used in pattern fill.
+
+2004-11-23 Ethan Merritt <merritt@u.washington.edu>
+
+ src/gplt_x11.c: Initialize mouse_format to null string. Fixes bug that
+ in some circumstances the mouse position is printed as random garbage.
+
+2004-11-21 Ethan Merritt <merritt@u.washington.edu>
+
+ Rearrange code so that pm3d support routines are available to both 2D
+ and 3D plots. The addition of pm3d code to 2D plots began in portions
+ of the WITH_IMAGE patch; remove the dependence on WITH_IMAGE to prepare
+ for more general use of pm3d colorspecs in 2D plots.
+ Introduce general checking for pm3d colorspecs in 2D plots. This fixes
+ a bug that the colorbox could only be drawn for "with image" plots if
+ the *first* plot used pm3d; subsequent plots were not checked.
+ Also, pm3d colorspecs were already usable for text coloring in 2D, but
+ no colorbox was drawn if they were used. Now it is.
+
+ * src/color.h src/gadgets.h : Move definition of t_colorspec to color.h
+
+ * src/color.h src/color.c src/graph3d.c src/graphics.c plot2d.c:
+ Remove #ifdef WITH_IMAGE from several code segments that are useful for
+ plot styles other than image.
+
+ * src/misc.c src/set.c src/misc.h: Move parse_colorspec from set.c
+ to misc.c and export it for use when parsing "with" options in both
+ 2D and 3D.
+
+ * src/plot3d.c src/pm3d.c src/pm3d.h src/graph3d.c:
+ Move set_plot_with_palette and is_plot_with_palette from plot3d.c into
+ pm3d.c so they can be shared by 2D and 3D code.
+
+ * src/graphics.c: Check for is_plot_with_palette() and modify layout of
+ 2D plots to include colorbox if it returns TRUE.
+
+ * src/color.c src/gadgets.c src/gadgets.h src/graph3d.c src/graphics.c:
+ Rename apply_textcolor() to be apply_pm3dcolor(), since it is usable for

+
+ * src/datafile.c (add_key_entry): Make sure all fields of newly

+
+ * demo/pm3d.dem: Turn off colorbox in the demo of corners2color.
+
+2004-11-13 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/specfun.c (f_erf f_erfc f_normal): Replace in-line rough
+ approximation for erf() and erfc() with calls to the internal

+ relevant to platforms that do not already provide math library
+ routines erf() and erfc(). Empirical tests show that this change

+
+2004-11-11 Ethan Merritt <merritt@u.washington.edu>
+
+ * demo/datastrings.dem: Add example of using a column both as a

+ (term.h): Rule generating this file disabled.
+ (gnuplot.html, gnuplot.info): Removed superfluous dependencies on

+ really worked.
+ (doc2gih.o, doc2hlp.o, doc2ipf.o, doc2rnh.o, doc2rtf.o): Build

+
+ * src/stdfn.h
+ * src/eval.c (gp_exp) src/specfun.c (f_gamma) src/standard.c (f_tanh):
+ Rename constant MINEXP to be E_MINEXP, since this is more in line with

+ current assumption that E_MINEXP == -88 if the build environment does
+ not provide a definition for DBL_MIN_10_EXP, probably in <float.h>.
+ On most machines this means that gnuplot's gamma() function should now

+ String variables - command line macros
+ --------------------------------------
+ Command line macros are indicated by the character @ preceding a

+
+ String variables - extra features
+ ---------------------------------
+ Autoconversion of strings to numerical values if encountered during
+ evaluation of a numerical expression. ("3" + "4.5" == 7.5) is true.
+ Autoconverion of integers to strings if encountered as an operand for
+ string concatenation. ("file" . 4 eq "file4") is true.
+
+ * configure.in: GP_STRING_VARS is #defined as 2 if these extra features
+ are desired. Defining it as 1 leaves the basic feature set enabled but
+ disables the extra stuff.
+
+ * docs/gnuplot.doc src/eval.c src/eval.h src/internal.c src/standard.c:
+ New routine pop_or_convert_from_string(), aliased to pop() during
+ numerical evaluation. Treat INTGR operand to f_concatenate as a
+ special case, promoting it to STRING.
+
+ * src/parse.c (const_express):
+ Suppress possible autoconversion to a number if the caller specifically
+ expects a string value to be returned.
+
+2004-10-27 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * src/term.c docs/gnuplot.doc: New 'set multiplot layout' options

+
+2004-10-25 Ethan Merritt <merritt@u.washington.edu>
+
+ String variables - basic functionality
+ --------------------------------------
+ Allow gnuplot variables to contain strings, and allow expressions
+ to operate on strings. Provide two pre-defined string-valued functions;
+ sprintf() is a wrapper for the the C language formatting routine of the
+ same name, gprintf() is a wrapper for the existing gnuplot-defined
+ format specifiers. All changes are bracketed by #ifdef GP_STRING_VARS.
+ Most places where gnuplot previously required a string constant will
+ now also accept a string variable or a string-valued expression.
+
+ * docs/gnuplot.doc:
+ * src/gp_types.h: STRING variable type
+
+ * src/internal.c src/internal.h src/eval.c src/eval.h src/parse.c
+ string operators (A . B) (A eq B) (A ne B)
+ string functions sprintf() gprintf()
+
+ * src/util.c (try_to_get_string) src/util.h: Modify the routine
+ try_to_get_string to accept string variables and functions. This one
+ place handles the syntax change for most gnuplot commands.
+ The main exceptions are 'plot', 'splot', and 'set label', which are
+ handled separately.
+
+ * src/scanner.c: accept . as a binary operator (string concatenation)
+
+ * src/datafile.c: evaluate string-valued functions in a 'using' spec
+
+ * src/mouse.c: set string variable MOUSE_CHAR when a key is pressed
+
+ * src/plot2d.c: accept a string variable 'plot <foo>'
+
+ * src/plot3d.c: accept a string variable 'splot <foo>'
+
+ * src/set.c: accept a string variable in 'set label <foo>'
+
+ * src/standard.c: int_error if a unary arithmetic operator is
+ applied to a string.

+ SourceForge patch #1052788.
+
+2004-10-23 Ethan Merritt <merritt@u.washington.edu>
+
+ * docs/gnuplot.doc: Reorganize the docs to give a separate section to

+ documentation.
+
+2004-10-22 Ethan Merritt <merritt@u.washington.edu>
+
+ * docs/gnuplot.doc: A very preliminary update of the "What's New"
+ section of the docs to track changes since the version 4.0 release.
+
+2004-10-21 Harald Harders <h.harders@tu-bs.de>
+
+ This patch introduces the possibilty to move many kinds of texts by an
+ offset in an arbitrary coordinate system. For example, tic marks, the
+ title, and labels can be moved by an offset given in 'character',
+ 'screen', 'graph', 'first', or 'second' coordinate system.
+ SourceForge patch #993422.
+
+ * docs/gnuplot.doc
+
+ * src/axis.c (get_position get_position_default):
+ New routine that accepts a default coordinate type when parsing offsets.
+
+ * src/axis.h: Add offset structure to axis tics.
+ * src/gadgets.h: Add offset structure to text labels.
+
+ * src/color.c (cbtick_callback draw_color_smooth_box)

+
+2004-10-20 Harald Harders <h.harders@tu-bs.de>
+
+ Introduce a new coordinate system 'character' that uses character width
+ and height as units. It is a 2d coordinate system similar to 'screen'.
+ The origin is the same as for 'screen'. SourceForge patch #993411.
+ The intended use is for setting label and text offsets in terms of
+ character size, and generalizing this to all places where an offset is
+ legal.
+
+ * NEWS docs/gnuplot.doc:
+ * src/axis.h src/axis.c (get_position_type) src/gadgets.h:
+ New coordinate system "character".
+
+ * src/graph3d.c (get_arrow3d place_labels3d place_arrows3d):
+ * src/graph3d.c (map3d_getposition map3d_position):
+ Track 3D coordinates internally as (int) rather than (unsigned int) so

+ character offsets.
+
+ * src/save.c (save_set_all) src/show.c (show_position show_arrowstyle):

+
+2004-10-20 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/gplt_x11.c (pr_font): Fix bug that whatever fallback font was used
+ for an unrecognized font request, that fallback would become the default
+ font for all future requests.
+
+2004-10-19 Juergen Wieferink <wieferink@freenet.de>
+
+ * src/set.c (parse_label_options): If the label has an associated point,
+ allow its type to be specified by "linestyle <n>".
+
+2004-10-19 Per Persson <persquare@mac.com>
+
+ Adding enhanced text support to terminal aqua.
+
+ * term/aquaterm.trm (ENHAQUA_put_text, ENHAQUA_open, ENHAQUA_flush,
+ ENHAQUA_writec): Added.
+
+ * docs/gnuplot.doc Add aqua to list of terminals with enhanced option.
+
+2004-10-18 Volker Dobler <v.dobler@web.de>
+ Ethan Merritt <merritt@u.washington.edu>
+
+ New plot style variant that reads individual point sizes from specified
+ input column. Examples:
+
+ plot 'foo' using 1:2:3 with points pt 5 pointsize variable
+ splot 'foo' using 1:2:3:4 with linespoints pt 5 ps variable
+ splot 'foo' using 1:2:3:4:5 with points pt 5 ps variable lt palette
+
+ * NEWS docs/gnuplot.doc: Document new variant of line/point style in

+
+ * src/graph3d.c (plot3d_points plot3d_points_pm3d): Check for variable
+ pointsize request and change point size before plotting.
+
+ * src/graphics.c (do_plot plot_points): Check for variable pointsize
+ request and change point size before plotting and in plot key.
+
+ * src/misc.c (lp_parse): Parse "pointsize variable" in with spec.
+
+ * src/plot2d.c (get_data eval_plots): Allow 3 columns of input for points,
+ with the extra column holding point size.
+
+ * src/plot3d.c (get_3ddata): Allow 4 columns of input for points with
+ variable point size in 4th column, plus a possible 5th column of pm3d
+ color information.
+
+ * src/save.c (save_set_all) src/show.c (show_linestyle): Print or save
+ "pointstyle variable" characteristic of line style.
+
+2004-10-18 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/be.trm term/cgm.trm term/emf.trm term/epslatex.trm term/fig.trm
+ term/gd.trm term/metapost.trm term/tgif.trm term/win.trm term/x11.trm:
+ Add a check in TERM_pointsize() so that negative point size is reset to
+ size 1.0. This has always been the case for the generic do_pointsize()
+ routine in term.c, but not all of the individual terminals did likewise.
+
+2004-10-17 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/plot2d.c (eval_plots) src/plot3d.c (eval_3dplots):
+ More stringent syntax test for bare numbers indicating line
+ type in backwards-compatibility mode.
+
+2004-10-17 Juergen Wieferink <wieferink@freenet.de>
+
+ * src/scanner.c (scanner): Terminate scan properly if an empty
+ substitution occurs at the end of a line. bug #1045695
+
+2004-10-16 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/plot3d.c (get_3ddata): Reorganize the code so that fewer
+ assumptions are made about what the plot must be based on the
+ number of columns, and so that the various 3D mapping modes share
+ the interpretations of columns other than the first three.
+
+ src/plot3d.c (get_3ddata): Initialize variables to shut off stupid
+ compiler warnings.
+
+ src/unset.c: #include hidden3d.c to pick up reset_hidden3doptions.
+
+2004-10-15 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/save.c (save_set_all): Do not try to save the current title and

+ Fixes strangeness with "test palette".
+
+2004-10-14 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/plot2d.c (get_data eval_plots): Defer adjustment of histogram
+ ranges until after the input file has been checked for valid data.
+ (fixes bug #1046894)
+
+ * src/datafile.c (df_parse_string_field): Handle missing field in
+ input file more gracefully. (bug #1046894)
+
+ * src/graph3d.c (map3d_position_r): Remove unused variables.
+
+2004-10-13 Harald Harders <h.harders@tu-bs.de>
+
+ * src/graph3d.c (map3d_position_r get_arrow3d):
+ Change the interface of the function map3d_position_r() to be similar
+ to map_position_r(). Now, map3d_position_r() does not need to get the
+ startpoint. This will make it easier to use it for all kinds of
+ relative coordinates as text offsets.
+
+ * src/graphics.c (get_arrow): map_position_r already handles the
+ relative position; no need to duplicate it in get_arrow.
+
+ * docs/gnuplot.doc: Mention that relative coordinates in log scale
+ imply a multiplicative rather than an additive offset.
+
+2004-10-12 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/graphics.c (place_labels): Add a TBOOLEAN flag to indicate whether
+ labels should be clipped against the current axis limits. Labels
+ generated by "set label <foo>" are never clipped; labels generated by
+ 'plot with labels' are clipped.
+
+ * src/graphics.c (fill_between): Improve clipping to handle 1st/2nd axes
+ and inverted axis range.
+
+2004-10-11 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * src/mouse.c (apply_zoom): Fix for reversed y-range in zoom by mouse
+ and "set view map".
+
+ * src/graphics.c (do_plot): Better warning for trying to use pm3d in a
+ 2d plot.
+
+2004-10-08 Petr Tobiska <tobiska@ure.cas.cz>
+
+ * term/metapost.trm (MP_arrow): Handle double-ended arrows also.
+
+2004-10-05 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/gplt_x11.c (pr_font): Release previous font every time a new one
+ is requested. This feels wrong to me since we know the old font will be
+ used again very soon, but otherwise there is a serious memory leak.
+
+ * src/gplt_x11.c (PaletteMake): (Daniel Sebald <daniel.sebald@ieee.org>)
+ Fix another tiny memory leak.
+
+ * src/plot3d.c (get_3ddata): Add missing #ifdef EAM_DATASTRINGS.
+
+ * configure.in: If --disable-datastrings is selected, then turn off
+ histogram support also since it is crippled without the
+ datastrings code.
+
+2004-10-05 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * config/config.cyg config/config.mgw config/config.os2: Added #defines

+
+2004-10-04 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/x11.trm (X11_graphics): Initialize font-tracking variable at the

+ windows with different default fonts).
+
+2004-10-04 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * src/gplt_x11.c (process_event): Added missing cmd_tried = 1.
+
+2004-10-03 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * src/gplt_x11.c (delete_plot): Fix small memory leak.
+
+2004-10-01 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/plot3d.c (get_3ddata): Allow explicit pm3d palette colors for line
+ and point styles in non-Cartesian mapping modes. (bug #1005775)
+
+2004-09-30 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/gd.trm: Change #ifdef GD2_VERS to #if (GD2_VERS >= 2) everywhere.
+
+ * term/emf.trm (EMF_set_font) term/tgif.trm (TGIF_set_font):
+ Fix longstanding problems with the set_font routines;

+
+2004-09-29 Ethan Merritt <merritt@u.washington.edu>
+
+ * demo/all.dem: Remove vector.dem again, since it turns out that it
+ breaks for any terminal type whose default value of 'set output' is
+ not the current display.
+
+ * demo/world2.dem: Set font explicitly to "Helvetica,7", since some
+ terminal drivers do not like the partial font spec ",7".
+
+ * src/hidden3d.c (set_hidden3doptions) src/hidden3d.h

+ term/svg.trm (SVG_set_font): Do not allow the font to be set to "";

+
+2004-09-29 Petr Mikulik <mikulik@physics.muni.cz>
+

+
+ * src/plot2d.c (eval_plots) src/plot3d.c (eval_3dplots): Wrap the code

+
+2004-09-24 Ethan Merritt <merritt@u.washington.edu>

+
+ * src/graph3d.c (plot_labels3d): Simplify place_labels3d by calling

+
+ * src/gadgets.c (get_offsets write_label) src/gadgets.h:

+
+ * demo/fit.dem demo/vector.dem demo/histograms2.dem:

+
+2004-09-20 Ethan Merritt <merritt@u.washington.edu>

+ for text in "{s}plot with labels textcolor palette ...".
+
+ * src/set.c (parse_colorspec): If "tc palette" is specified with no
+ further suboptions, default to "tc palette z".
+
+ * src/plot3d.c (get_3ddata): Allow palette color options in cylindrical
+ and spherical coordinate modes also.
+
+2004-09-09 Harald Harders <h.harders@tu-bs.de>
+
+ * term/post.trm: Update the comment on plot-time evaluation of
+ PostScript language level support.
+
+2004-09-09 Shigeharu Takeno <shige@iee.niit.ac.jp>
+
+ * docs/gnuplot.doc, term/cgm.trm, term/eepic.trm, term/emf.trm,
+ term/epslatex.trm, term/post.trm: Fix misprints in gnuplot manual (#15).
+
+2004-09-07 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/gplt_x11.c (process_event) term/x11.trm: Provide a command line
+ option (-ctrlq) and an X resource (gnuplor*ctrlq: true) that disable
+ trapping the 'q' and '<space>' keystrokes in the plot window, instead
+ trap <ctrl>q and <ctrl><space>. This option allows the 'q' and
+ '<space>' keystrokes to be treated like all other keystrokes during
+ "pause mouse key" and other mousing operations.
+
+
+2004-09-06 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * configure.in (AC_PREREQ): Bumped to 2.58, to avoid problems with
+ missing AC_HEADER_STDBOOL.
+
+2004-09-06 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * configure.in: The --enable-image option requires general binary data
+ file code. Ensure --disable-binary-data-file is not in the option list
+ if only --enable-image is activated.
+
+2004-09-06 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * config/config.cyg config/config.mgw config/config.os2: Added #defines
+ for "with image".
+
+2004-09-03 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * src/breaders.c src/datafile.c: Get rid of compiler warnings.
+
+2004-09-03 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * src/datafile.c: Changed default value of datafile endianess after
+ reset: from variable df_bin_file_endianess_reset = DF_LITTLE_ENDIAN to
+ #define DF_BIN_FILE_ENDIANESS_RESET THIS_COMPILER_ENDIAN.
+
+2004-09-03 Shigeharu Takeno <shige@iee.niit.ac.jp>
+
+ * demo/image.dem: Added endian=little where necessary.
+
+2004-09-02 Ethan Merritt <merritt@u.washington.edu>
+
+ * demo/all.dem: Include demos for candlesticks, multiplot, and
+ enhanced text mode in the all.dem script used by "make check".
+
+2004-09-01 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/gd.trm (PNG_set_color PNG_image) term/pdf.trm (PDF_image)
+ term/post.trm (PS_image): Change call from rgb255_from_gray() to
+ rgb255maxcolors_from_gray(). Fixes color mapping with 'set palette
+ maxcolors'.
+
+ * src/getcolor.c: Remove unused routine rgb255_from_gray.
+
+ * term/gd.trm: Add WITH_IMAGE support for gif terminal also.
+
+2004-09-01 Lars Hecking <lhecking@nmrc.ucc.ie>
+
+ * demo/Makefile.am.in: Add new binary demo files to Makefile.am
+ target.
+
+ src/Makefile.am: Add missing binary.h to bf_test_SOURCES.
+
+2004-09-01 Daniel Sebald <daniel.sebald@ieee.org>
+
+ * NEWS: Updated.
+
+ * configure.in: Added enable and define switches to activate new
+ portions of code:
+ WITH_IMAGE (--enable-with-image) code for plotting images
+ WITH_IMAGE_VERIFY_ALL_PIXEL_LOCATIONS (--enable-image-grid-verify)
+ code for verifying every point in image grid is uniformly spaced
+ BINARY_DATA_FILE (--enable-binary-data-file) code to allow reading
+ general binary data files
+ BINARY_X11_POLYGON (--enable-binary-x11-polygon) code for X11 that
+ allows transferring polygon information as binary values rather
+ than ASCII, to save space in plot buffers
+
+ * demo/all.dem: Added inclusion of image.dem.
+
+ * demo/asciimat.dat demo/blutux.rgb demo/demo.edf demo/scatter2.bin
+ demo/sine.bin demo/using.bin: New datafiles required by image.dem.
+
+ * demo/image.dem: New demo to illustrate and test various new image
+ and binary and matrix data file features.
+
+ * docs/gnuplot.doc: Added documentation for image features and general
+ binary file syntax. Also, removed language indicating gnuplot matrix
+ binary is restricted to `splot`, as it now can be used for images in
+ `plot`.
+
+ * src/Makefile.am: Added gplt_x11.h to gnuplot_SOURCES list and
+ gnuplot_x11_SOURCES list. Added bin_hook.c to gnuplot_SOURCES list and
+ removed binary.c and binary.h from this list.
+
+ * src/README: Added a discussion of technical details about how the
+ formulas for properly orienting an image and passing that to the
+ terminal driver are derived. They can be arcane if just looking at the
+ code inside plot_image_or_update_axes(). Same goes for the details
+ about sending binary data to gnuplot_x11 for images. It requires a
+ simple heuristic encoding scheme to avoid a few particular characters
+ from the data stream and can appear confusing at first sight.
+
+ * src/bin_hook.c: A new, short file to include binary.c in the source
+ tree if BINARY_DATA_FILE is not defined. Otherwise, binary.c is no
+ longer required.
+
+ * src/breaders.h: An example of how to read a header in a particular
+ file format and fill in the general binary structure details. Not
+ completely sure just yet how this should be integrated into gnuplot.
+
+ * src/color.c (draw_color_smooth_box): Added an option for `plot` mode
+ for use in images with a palette.
+
+ * src/color.h: Adjusted function definition for change noted above.
+
+ * src/command.c: Now save a new property is_cb_plot to determine if a
+ color box can be part of the plot in question.
+
+ * src/command.h: Added declaration of is_cb_plot variable.
+
+ * src/datafile.c: Extensive additional code for interpreting general
+ binary keyword syntax. Changed df_readline() to df_readascii() and
+ added a new file df_readbinary() analogous to df_readascii(). A new
+ df_readline() chooses which of these two to utilize. Code for reading
+ binary and ASCII matrix format file was moved to df_readbinary(). This
+ means other files in the source tree could be restructured so that the
+ routine df_readline() is the only method to bring data into gnuplot.
+
+ * src/datafile.h: Declarations for new functions as part of code noted
+ above. Also, there are a few new enumerations and, most importantly,
+ the definition for the structure containing information about general
+ binary records.
+
+ * src/fit.c (fit_command): Altered df_open() argument to include the
+ plot mode MODE_QUERY.
+
+ * src/getcolor.c: Reactivated rgb255_from_gray(), required for images.
+
+ * src/gp_types.h: Added IMAGE and RGBIMAGE to PLOT_STYLE enumeration.
+
+ * src/gplt_x11.c: Extensive additional code for handling images in
+ binary data format, polygons in binary data format, and an endianess
+ check to determine if bytes need be swapped. A simple, short encoding
+ scheme is used for binary data to avoid a couple special characters in
+ the data stream.
+
+ * src/gplt_x11.h: A new header file to go along with gplt_x11.h
+ containing definitions for code characters sent across pipe. Also some
+ definitions for translation characters in the binary encoding scheme.
+
+ * src/graph3d.c (do_3dplot): Added a plot_mode of MODE_SPLOT to
+ argument of draw_color_smooth_box(), as now that can also be done for
+ `plot`. Also, added cases of IMAGE and RGBIMAGE to plot style switch.
+
+ * src/graphics.c: Added plot_image_or_update_axes(), a new image
+ plotting routine. The new routine is fairly long and arcane in spots.
+ The README file contains details to clear up obscure parts. Added the
+ cases IMAGE and RGBIMAGE to the switch statement for plot style. Also,
+ there is code for making room for a color box on the plot, followed by
+ a call to draw_color_smooth_box() where appropriate.
+
+ * src/graphics.h: Added definitions PLOT_IMAGE(), SPLOT_IMAGE() and
+ UPDATE_AXES_FOR_PLOT_IMAGE() to make plot_image_or_update_axes() seem
+ more intuitive.
+
+ * src/misc.c: Added 'image' and 'rgbimage' to list of plot styles in
+ error message indicating valid styles.
+
+ * src/mouse.c (builtin_toggle_log): For plots having a color box
+ property, allow changing the color box to logarithmic scale.
+
+ * src/plot2d.c: Many small alterations to case statements, etc. to
+ integrate IMAGE and RGBIMAGE plot styles. Also, added MODE_PLOT to
+ df_open() argument list for binary data files.
+
+ * src/plot3d.c: Similar to plot2d.c, many little changes made to
+ incorporate IMAGE and RGBIMAGE plot styles. Also, for general binary
+ there is no longer need for df_3dmatrix(), so that call was removed.
+ Added MODE_SPLOT to argument list of df_open().
+
+ * src/save.c (save_data_func_style): Write `image` or `rgbimage` to
+ file if appropriate plot style.
+
+ * src/set.c (set_command/set_palette_file): Added call to routine
+ setting defaults for binary data files if `binary` is specified as
+ part of `set` command. / Added MODE_QUERY to list of arguments for
+ df_open().
+
+ * src/show.c (show_datafile): Now show information about binary data
+ file settings and details about binary variable sizes in bytes for the
+ compiler under which gnuplot was built.
+
+ * src/tables.c (show_style_tbl): Added `image` and `rgbimage` to table.
+
+ * src/term_api.h (TERMENTRY): Added image() prototype function to
+ TERMENTRY structure as well as an enumeration for image type as an
+ argument to image() routine.
+
+ * src/unset.c (unset_command/reset_command): Added call to routine that
+ clears the binary data file record information.
+
+ * src/util3d.c: Added a routine map3d_xy_double() to retain more
+ accurate coordinates necessary for checking uniformity of the image
+ grid via hyperplane concepts. It is repetition of existing code,
+ but there is a note and define switch for code-reuse.
+
+ * src/util3d.h: Added declaration for map3d_xy_double().
+
+ * term/README: Added note about how to properly use image() terminal
+ function.
+
+ * term/aquaterm.trm: Per Persson added an implementation of the image()
+ terminal function, AQUA_image().
+
+ * term/dumb.trm: Ethan Merritt added a space filler for the image()
+ terminal function location of TERM_TABLE.
+
+ * term/epslatex.term: Added PS_image() to structure for image() in
+ TERM_TABLE. PS_image() is in post.trm.
+
+ * term/gd.trm: Ethan Merritt added a routine PNG_image() for the
+ TERM_TABLE entry of image(). Also, a supporting routine PNG_set_color
+ was created.
+
+ * term/pdf.trm: Ethan Merritt added a routine PDF_image() and entry
+ into the TERM_TABLE for image support for PDF files.
+
+ * term/post.trm: Added a routine PS_image() and appropriate entry in
+ the TERM_TABLE for image support in PostScript files. There is also a
+ supporting routine PS_encode85() for encoding binary image data in
+ ASCII85 data format.
+
+ * term/pslatex.trm: Added PSLATEX_image() to structure for image() in
+ TERM_TABLE. It uses a simple call to PS_image(), which is in post.trm.
+
+ * term/svg.trm: Added space filler in TERM_TABLE for image() function.
+
+ * term/x11.trm: Added X11_image() function and entry in TERM_TABLE.
+ The new image routine contains code for a simple, heuristic encoding
+ scheme to prevent a couple specific bytes from being in the image data
+ stream. Similarly, X11_filled_polygon() and X11_set_color() were
+ altered to use the same scheme to reduce the amount of characters
+ inside the plot buffer.
+
+2004-08-27 Per Persson <persquare@mac.com>
+
+ * src/term.c (init_terminal): Make aqua the default terminal on
+ Mac OS X if AquaTerm is installed.
+
+2004-08-27 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/gd.trm (PNG_vector): More specific test for libgd support of
+ antialiasing. Versions 2.0.0 -> 2.0.11 were not correctly handled by
+ the previous test.
+
+2004-08-25 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/plot.c (main): Call term->options() on entry if the default
+ terminal type is png, jpeg, or tgif. Without this, setting GNUTERM
+ to this driver type causes a segfault due to incomplete initialization
+ of the driver data structures. I believe this call to term->options()
+ would be OK for all other drivers as well, but to be on the safe side
+ I added it only for the drivers I know will segfault without it.
+
+ * term/gd.trm: New option to generate truecolor png images.
+ set term png .. {{no}truecolor} ..
+
+ * term/gd.trm (PNG_vector): Use anti-aliasing for vectors if possible.
+ This does not affect palette-based PNG images, so far as I can tell,
+ but does work for both JPEG and TrueColor PNG images.
+
+2004-08-25 Per Persson <persquare@mac.com>
+
+ * term/aquaterm.trm (AQUA_options): make options order-independent;
+ replace isstring+quote_str with try_to_get_string();
+ allow "font" as a synomym for "fname".
+
+2004-08-23 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/xlib.trm (Xlib_text): Leave output file open so that it is
+ possible to plot multiple frames without another 'set term xlib'.
+
+ * svg.trm (SVG_options): allow "font" as a synonym for "fname";
+ replace isstring+quote_str with try_to_get_string();
+ new option "linewidth <n>".
+
+ * pdf.trm (PDF_options): make options order-independent;
+ replace isstring+quote_str with try_to_get_string();
+ allow "font" as a synomym for "fname";
+ new option "linewidth <n>".
+
+ * post.trm (PS_options): allow "font" as a synonym for "fname"
+
+ * fig.trm (FIG_options): allow "linewidth" as a synonym for "thickness".
+
+2004-08-23 Shigeharu Takeno <shige@iee.niit.ac.jp>
+
+ * docs/gnuplot.doc: Fix misprints in gnuplot manual (#14).
+
+2004-08-20 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/set.c (set_termoptions): Only call term->options for
+ terminals that actually support the option in question.
+
+ * src/term.c (write_multiline) term/driver.h: Remove unused
+ function set_font_null; instead mark lack of font support by
+ initializing this TERM_TABLE entry to NULL. Fixes segfault
+ if font is checked before terminal is initialized, and allows
+ non-destructive test of font support.
+
+2004-08-20 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/set.c (set_termoptions): Quietly ignore the command if there
+ is no current terminal.
+
+2004-08-19 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/set.c (set_termoptions): Fill in basic implementation of this
+ function that allows changing one characteristic of the current
+ terminal. So far the only allowed changes are the default font and
+ {no}enhanced text mode.
+
+ * demo/enhancedtext.dem: Use 'set termoption enhanced' (new command)
+ to force enhanced text mode regardless of current terminal type.
+
+ * docs/gnuplot.doc: Document 'set termoption <foo>'.
+
+ * NEWS: Update NEWS file to cover post-4.0 development work.
+
+2004-08-18 Volker Dobler <v.dobler@web.de>
+
+ * src/term.c (term_end_plot term_start_multiplot term_end_multiplot):
+ Implement auto-layout of multiplots with specified number of rows
+ and columns.
+
+ * docs/gnuplot.doc demo/layout.dem: Document and illustrate use
+ of 'set multiplot layout'.
+
+2004-08-18 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/svg.trm: More consistent handling of default background and font.
+
+2004-08-17 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/eval.c (real imag magnitude angle): Move error message handling
+ into default case of switch statements (prevents compiler warnings).
+
+ * src/plot2d.c (eval_plots) src/graphics.c (init_histogram):
+ Replace instance of isstring + quote_str with try_to_get_string().
+ Make histogram_title a dynamically allocated string rather than a fixed
+ length char constant.
+
+2004-08-15 Ethan Merritt <merritt@u.washington.edu>
+
+ * demo/histograms.dem: Revise bmargin settings to work with the revised
+ bmargin handling in graphics.c (2004-07-25).
+
+ * src/plot2d.c (eval_plots): Fixed bug in "newhistogram 'title' ..."
+ that caused the title to be ignored if there were no other options
+ specified.
+
+2004-08-13 Shigeharu Takeno <shige@iee.niit.ac.jp>
+
+ * src/term.c (enhanced_recursion): Pass unescaped backslash character
+ through to PostScript output in enhanced text mode. This is necessary
+ for Shift-JIS character encoding to work in enhanced mode (the non-
+ enhanced mode already does this). Bug report #998479.
+
+2004-08-13 Ethan Merritt <merritt@u.washington.edu>
+
+ * docs/gnuplot.doc: Re-word the filledcurves section according to
+ suggestions from Petr Mikulik.
+
+ * term/post.trm: Rename new option once again: set term post {level1}
+ (naming history: nolevel2 -> ai -> level1). Audit code to confirm that
+ in fact it excutes only commands required by PostScript Level 1.
+
+ * src/save.c (save_tics) src/show.c (show_tics): Save tic level for
+ each explicit user-added tic. Fixes bug #1008869.
+
+2004-08-12 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/post.trm: Rename 'nolevel2' option to 'ai', since its primary
+ use may be to generate output compatible with Adobe Illustrator.
+
+2004-08-11 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/gplt_x11.c (exec_cmd): Set line properties to CapRound, JoinRound
+ while drawing plot symbols. This works around a very odd bug that
+ causes the symbols to be drawn incorrectly for some X-server settings.
+ Also modify plot symbol code so that the symbols are always drawn with
+ a 1:1 aspect ratio (crosses always fit in a square) rather than
+ tracking the aspect ratio of the current plot window.
+
+2004-08-10 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/set.c (parse_colorspec): Allow people to set the text color
+ to background (tc lt -2) if they really want to.
+
+2004-08-09 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/command.c: Remove unused prototype.
+
+ * src/getcolor.c: Conditionally remove unused prototype during
+ compilation of gnuplot_x11.
+
+ * src/plot2d.c (eval_plots) src/plot3d.c (eval_3dplots)
+ src/set.c (set_tic_prop): Continue replacement of isstring +
+ m_quote_capture with try_to_get_string().
+
+ * src/command.c (history_command): Code cleanup; convert to use
+ try_to_get_string(). Code is still full of little memory leaks.
+
+ * term/post.trm: Fix '%' characters in output format.
+
+2004-08-08 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/util.c src/util.h: New routine try_to_get_string() that combines
+ isstring() and m_quote_capture(). The intent is to switch call sites
+ over to using this new routine, and then extend it to handle string
+ variables as well as quoted inline string constants.
+
+ * src/contour.h: Revised declaration of contour_format[].
+
+ * src/set.c src/command.c: Begin wholesale replacement of isstring()
+ and m_quote_capture/quote_string with new routine try_to_get_string().
+
+2004-08-07 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/set.c (set_print set_output): Do not chop whitespace from the
+ front of input string; it causes a segfault when the string is freed.
+ If we really need to strip whitespace from filenames, it should be done
+ in a routine shared by all callers.
+
+2004-08-06 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/graphics.c (place_arrows): Restore default text color after
+ drawing all the arrows. Fixes bug #1004765.
+
+2004-08-02 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/gd.trm src/term.h configure.in src/show.c (show_version):
+ GIF support is back in libgd as of version 2.0.28 (July 2004).
+ At last we can use the same driver for png, gif, and jpeg.
+
+ * term/gif.trm term/png.trm: Remove these old drivers.
+
+ * src/makefile.all docs/Makefile.in: And remove them as make targets.
+
+ * src/command.h src/command.c (load_command): Remove macro that was
+ used in only one place; clean up code order as prep for applying
+ string variable patches.
+
+2004-08-01 Ethan Merritt <merritt@u.washington.edu>
+ Harald Harders <h.harders@tu-bs.de>
+
+ * term/post.trm: Introduce a boolean value PSLevel2 into the PostScript
+ prolog, and use it to determine whether pattern-fill is defined using
+ PostScript Level 2 primitives or via a Level 1 solid fill. Introduce a
+ corresponding option 'set term post ... {no}level2'. Setting level2
+ to false either via 'set term' or by editing the output PostScript file
+ accommodates older printers and older versions of Adobe Illustrator.
+
+2004-07-31 Harald Harders <h.harders@tu-bs.de>
+
+ * term/post.trm (PS_common_init PS_put_text ENHPS_put_text):
+ Check for black text only option in the PostScript code itself,
+ rather than at the time the plot is generated. This allows you to
+ change your mind later by editing one line in the PostScript file.
+
+2004-07-30 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * src/show.c (show_key): Fix memory leak by making the variable in
+ question a local to the switch case that uses it.
+ (show_styles): Remove const-ness modifying cast.
+
+ * src/save.c (save_data_func_style): Marked pointer argument
+ 'which' as const.
+
+ * src/save.h (save_data_func_style): Prototype updated
+ accordingly.
+
+2004-07-29 Ethan Merritt <merritt@u.washington.edu>
+
+ * docs/gnuplot.doc: Fix the alphabetical order of plot style
+ doc sections.
+
+2004-07-29 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * src/util.c (PRINT_SPACES_UNDER_PROMPT): Protect against
+ NULL prompt.
+
+2004-07-27 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ Bugfix: caret position of error messages in multiplot modes was
+ wrong.
+
+ * src/util.c (current_prompt): New variable holding the currently
+ used prompt string.
+ (PRINT_SPACES_UNDER_PROMPT): Use current_prompt instead of global
+ PROMPT macro. Use a pointer loop instead of a counter.
+ (PRINT_SPACES_UNDER_PROMPT, PRINT_SPACES_UPTO_TOKEN): Enclosed
+ macro body in do .. while(0).
+ (os_error, int_error, int_warn): Use current_prompt instead of
+ global macro PROMPT.
+
+ * src/util.h (current_prompt): Declare.
+
+ * src/command.h (PROMPT): Moved this global macro into command.c.
+
+ * src/command.c (PROMPT): Moved macro to here.
+ (read_line) [VMS]: Update new global variable current_prompt.
+ (read_line) [!VMS]: Likewise.
+
+2004-07-25 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ Code style changes: get rid of register keywords. Don't put
+ parens around simple variables or term->element names.
+
+ * src/graphics.c (boundary): If bmargin was set by user, key below
+ should not modify ybot. Reindented.
+
+ (key_cols): Made local to boundary(), the only function using it.
+
+2004-07-24 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/parse.c (cleanup_udvlist): Fix memory leak; if udv structure
+ is freed, free its dynamically allocated name also.
+
+ * src/command.c (print_set_output): Fix memory leak; free old
+ filename before setting a new one.
+
+ * src/plot3d.c: Remove unnecessary #include "plot2d.h".
+
+2004-07-22 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * src/util.h (os_error, int_error, int_warn, graph_error):
+ Reverted change to prototypes for non-ANSI case back from (void)
+ to ().
+
+ * src/fit.c (Dblfn): Likewise.
+
+2004-07-21 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/graphics.c (plot_bars plot_betweencurves): If the current
+ terminal does not support filled_polygons, then fall back to
+ yerrorbars plot style as per the documentation.
+
+2004-07-21 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * term/post.trm (PS_make_header): Moved prototype into PM3D-only
+ section.
+
+2004-07-21 Lars Hecking <lhecking@nmrc.ucc.ie>
+
+ * demo/Makefile.am.in: Add labelplot.pdb and nearmap.csv to
+ Makefile.am target.
+
+2004-07-19 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/graphics.c (do_plot): Write the key titles using

+
+ * term/post.trm (PS_filled_polygon): The polygon fill code was

+ in pattern-filled fillcurves.
+
+ * term/post.trm (PS_filled_polygon): Restore Petr's preferred
+ compact format for the quadrangles that make up a pm3d surface,

+ coordinates specified. E.g.:
+ plot 'datafile' using 1:2:3 with labels
+ splot 'datafile' using 7:8:9:4 with labels
+
+ New internal functions specific to the 'using' option that specify
+ that string data from a datafile column is to be used for tic labels,
+ or that string data from a datafile row is to be used for plot key
+ titles. E.g.:
+ plot '-' using 0:2:xticlabels(1) title 2 with boxes
+ xxx "2001"
+ Jan 123
+ Feb 456
+ Mar 78
+ e
+ This will plot a histogram with each an x-axis tic label under
+ each box: "Jan", "Feb" etc. The plot key will list the plot with
+ title "2001".

+ terminal supports mousing at all, but we don't yet have such a
+ flag.

+
+ * graph3d.c (do_3dplot): Fixed set_color(z2cb( cb2gray(cntrs->z))

+
+ * src/command.c src/command.h src/mouse.c src/gplt_x11.c

+ `pause mouse keypress` option behaves exactly as `pause mouse` except
+ that the pause can be terminated by a keystroke while the plot window
+ has focus. On return, the variable MOUSE_KEY contains the mouse button
+ number if the pause terminated on a mouse click, otherwise it contains
+ the key code of the key that was pressed. Normal ascii characters will
+ return their ascii code; other keyboard keys are assigned codes from a
+ table in mousecmn.h. The command may be shortened to `pause mouse key`.

+ * src/pm3d.c src/term.c term/hpljii.trm: SF bug #953887 non-portable C
+ code (prototypes & TBOOLEAN): input parameter for routines cannot be
+ char, they must be int.
+
+2004-05-21 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/gplt_x11.c (mainloop): Add a 100 usec delay to the event flush
+ loop, so that if the other end of the pipe is jammed (gnuplot STOPPED)
+ it doesn't monopolize CPU cycles. Fixes user-triggered error condition
+ reported in bug #930426.
+
+2004-05-21 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * src/graphics.c (plot_boxes): Clip lower border of
+ boxxyerrorbars, too.
+ (do_plot): Regrouped master switch over plot types. Draw box
+ first in BOXERROR mode, to keep the lower part of the errorbar
+ visible.
+
+ * src/util.c (mant_exp): Extend technique for rounding exponents
+ depending on the printf format precison of the mantissa to format
+ specifiers %l and %L used for log bases other than 10. Fixes SF
+ bug #851685.
+
+2004-05-20 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * term/debug.trm (DEBUG_arrow): Fix type of 'head' argument
+ overlooked in earlier global change.
+
+ * src/plot2d.c (get_data): Fix mininum number of columnts for
+ boxerrorbars style. Fixed handling of 4-column boxerrorbars in
+ case of "set boxwidth -2" to match the documentation.
+
+ * src/graphics.c (plot_impulses): Fix bug in clipping of impulses
+ for out-of-range points. Was using an integer value to store a
+ floating-point temporary number.
+
+ * src/plot2d.c (print_table): Make the table terminal output two
+ blank lines at the end of each curve_points structure, to allow
+ selection of individual datasets via the 'index' option.
+
+ * docs/doc2texi.el (d2t-handle-html): Handle anchor-only <a> tags
+ more sensibly: output them to the texinfo file as a @c comment.
+ Patch from Shigharu Takeno.
+
+ * docs/gnuplot.texi: Regenerated.
+
+2004-05-19 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * src/mouse.c: Fix broken zoom history with a log axis.
+
+2004-05-17 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * src/mouse.c src/win/wpause.c: Support for "pause mouse" in Windows
+ terminal.
+
+2004-05-16 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/graphics.c (boundary): prevent plot from flipping upside-down
+ if the title or key take up too much vertical space.
+
+ * term/post.trm: Add explicit default case to encoding switch.
+
+2004-05-09 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/x11.trm: Reduce time delay in waitforinput() from 1 sec
+ to 100 usec.
+
+2004-05-09 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * docs/gnuplot.doc src/term_api.h src/term.c term/post.trm: Add support
+ for CP1250 character encoding (Central and Eastern Europe encoding on
+ MS-Windows).
+
+2004-05-09 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * config/README: Clean up some of the descriptions.
+
+2004-05-07 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/x11.trm: Add an explicit "noenhanced" option to set term x11,
+ since otherwise once you select enhanced text you cannot turn it off
+ again.
+
+2004-05-07 Franz Bakan <fbakan@users.sourceforge.net>
+
+ * src/os2/gclient.c: SF bug #940596. Match menu items "GnuplotPM ->
+ Mouse -> Coords format -> ..." to the text actually printed.
+
+2004-05-06 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * src/win/wtext.c (WndTextProc): Fix unbelievably old
+ long-standing bug: dragging the scroll bar "thumb" around didn't
+ work, because the method of acccessing the position was completely
+ wrong.
+
+2004-05-04 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * src/set.c (set_range): Fix SF bug #946900: buggy interaction of
+ 'set view map' with 'set yrange'.
+ (set_view): Make error message string variables static and const
+ to preserve some stack.
+
+2004-05-03 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/mouse.c, term/x11.trm: Move handling of mouse click after
+ 'pause mouse' from mouse.c to x11.trm. This removes an otherwise
+ unnecessary do_string("replot") from mouse.c, and instead adds an
+ explicit check for mouse button release in X11_waitforinput().
+
+ * demo/mousevariables.dem: Add a comment after final pause command.
+
+ * src/set.c src/unset.c: Call gp_strdup() rather than strdup() as
+ otherwise the test in ./configure is pointless, and gnuplot fails
+ to link on systems without strdup().
+
+ * term/x11.trm: Redefine VMS-only macro to allow if/then/else
+ constructs: GO(x) = do {} while (0)
+
+ * src/show.c: Protect call to add_history() with a test for the
+ presence of READLINE support.
+
+2004-04-30 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * docs/gpcard.tex: Remove duplicated X11 terminal entry.
+
+2004-04-29 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * docs/gnuplot.doc: Fix description of default format being "% g"
+ instead of "%g".
+
+2004-04-26 Petr Mikulik <mikulik@physics.muni.cz>
+
+ * docs/gnuplot.doc: New section "Gnuplot-defined variables". Reference
+ function defined(x) from section "User-defined variables".
+
+2004-04-24 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/gplt_x11.c: Correct the placement of rotated text to account
+ for the difference in x and y coordinate scaling. This greatly
+ improves the rendering of rotated text in enhanced text mode.
+
+2004-04-22 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * src/axis.c (set_cbminmax): Don't bail out if cbrange is empty.
+ Let the caller handle it by auto-extending the range, as usual.
+
+ * src/command.c (read_line): Fix bug where growing the line buffer
+ interfered with handling of backslash-newline continuations.
+
+2004-04-21 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * demo/Makefile.am.in (check-noninteractive, check-interactive):
+ keep the previous $PATH at the end of the one set for running the
+ newly built, not yet installed gnuplot. Needed so Cygwin binaries
+ can find Cygwin1.dll, even if it's not installed in the Windows
+ DLL path.
+
+2004-04-20 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
+
+ * docs/gnuplot.texi: Regenerated.
+
+ * docs/gnuplot.doc: Fixed missing leading blanks broken during URL
+ updates.
+
+ * docs/Makefile.in ($(srcdir)/gnuplot.texi): Fix missing blank in
+ file copying rule.
+
+2004-04-17 Ethan Merritt <merritt@u.washington.edu>
+
+ * term/x11.trm: Clear all I/O locks when X11_reset is called.
+ This is a more generic fix for the problem addressed by the patch
+ of 2004-04-13, and covers cases such as a remote X-server failing
+ to respond. Even without this patch the connection will eventually
+ timeout, but with the patch you can ctrl-C out rather than waiting.
