+
+ * 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

+ * src/axis.c (gen_tics): Correct the calculation of last minitic
+ position to be plotted on a log-scale axis. Bug #1223149.
+
+ * src/term.c (write_multiline): Fix trivial line-counting bug.

+
+ * src/set.c (parse_label_options): Fix incorrect ordering of
+ declaration/initialization. Non-gcc compilers didn't like it.

+
+ * src/graphics.c (boundary): Allow space for zeroaxis tic labels when
+ zeroaxis is near plot border. Bug #219867 swatted after 5 years!

+ 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
+ same time. No change to basic syntax or behaviour of tics, but the
+ extra key word "add" in a "set [xuz]tics ..." command causes the
+ requested tics to be added to the current ones rather than replacing
+ them.

+
+ * src/graphics.c (plot_image_or_update_axes): Use gp_alloc rather
+ than malloc. Bug #1254314.
+
+ * src/gplt_x11.c src/getcolor.c: Check for NULL return from malloc().
+ Bug #1254314.
+
+ * demo/all.dem: Fixed mis-matched quotes around "rgb_variable.dem".

+
+ * src/command.c (string_expand): Fix bug in macro handling; escaped
+ quotes were not recognized.
+
+2005-09-16 Ethan Merritt <merritt@u.washington.edu>
+
+ * src/graph3d.c (draw_3d_graphbox): Treat placement of Z-axis label in
+ the same way as those for the X and Y axes.
+
+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.

+ Fix bugs in fontfile handling of ps terminal. Document &q
