2014-08-20 Ethan A Merritt <[email protected]>
* Branchpoint for 5.0 (cvs tag -b branch-5-0-stable)
2014-08-20 Ethan A Merritt <[email protected]>
* src/wxterminal/gp_cairo.c: Distinct empirical scale factors for
dashlength used by pngcairo, pdfcairo, and wxt.
* term/emf.trm: Scale dashlength with current linewidth.
2014-08-18 Ethan A Merritt <[email protected]>
* src/graphics.c (place_arrows) src/graph3d.c (place_arrows3d):
Only invoke the arrowheads only code if there really is an arrowhead.
2014-08-18 Hans-Bernhard Broeker <[email protected]>
* config/mingw/Makefile (VPATH): Drop $W from VPATH. Necessary to
avoid circular dependency on wgnuplot.mnu
(%.$(O)): Use pattern rule instead of VPATH to build Windows
source files.
(VERSIONING): Avoid inverted logic in makefile conditional.
(console, windows, pipes): Simplify by letting the default rule in
the sub-make handle things.
(default, all): Versioning is really needed by $(TARGET) rule,
so let that handle constructing it.
($(TARGET)): Do VERSIONING first, drop dependencies on icon files.
(%.o): Use pattern rules to build Qt source files. Much simpler
than spelling it out long hand for every single source file.
2014-08-15 Ethan A Merritt <[email protected]>
* src/bf_test.c src/Makefile.am src/binary.* (removed)
config/makefile.os2 config/makefile.dj2 config/makefile.cyg
config/cygwin/Makefile config/mingw/Makefile config/msvc/Makefile:
Remove bf_test dependence on all other gnuplot files and libraries.
This makes binary.c and binary.h superfluous.
Bugs #1412 #1451
* src/makefile.all src/makefile.awc: Remove mention of binary.o
* config/*/Makefile: Remove alloc and binary from bf_test dependencies
* src/graphics.c (place_objects) src/set.c (set_obj):
Apply default rectangle style at the time of a "set object rect"
command rather than waiting until the rectangle is drawn. This prevents
the default style line/dash settings from overriding explicit rectangle
commands.
Bug #1460
* src/save.c (save_linetype): Bugfix - dashtype was being saved only if
there was also a point type.
* src/gadgets.c (apply_pm3dcolor): Don't clobber current dashtype by
calling term->linetype(LT_BLACK). Call term->set_color(BLACK_COLORSPEC)
instead.
* src/graphics.c (place_arrows) src/graph3d.c (place_arrows3d):
Force solid lines for arrow heads.
2014-08-15 Shigeharu Takeno <[email protected]>
* src/gplt_x11.c: For single byte fonts gnuplot_x11 uses a list of
previously used fonts to speed up the search for a new target font.
Now we add an equivalent for multi-byte font search.
2014-08-14 Ethan A Merritt <[email protected]>
* src/graphics.c (do_rectangle) src/graph3d.c (map3d_position_r)
demo/rectangle.dem: Fix y extent and clipping of rectangles with
negative y coord or inverted axes.
Bug #1462
2014-08-05 Ethan A Merritt <[email protected]>
* src/mouse.c (event_buttonpress): Remove extraneous event_reset.
2014-08-02 Ethan A Merritt <[email protected]>
* src/misc.c (parse_colorspec): Apply user-defined line colors
to text color also.
Bug #1452
src/misc.c src/save.c src/set.c src/term.c src/term_api.h:
Store custom dashtype string as a constant length character array
rather than a dynamically allocated string. This fixes memory
leakage that happened whenever a linetype using dashes was discarded.
2014-08-01 Ethan A Merritt <[email protected]>
* src/mouse.c (event_buttonpress): Trap mouse button click on
press rather than on release so that "pause mouse {button1|any}"
takes precedence over a key binding to the mouse button.
Bugfix
2014-07-30 Ethan A Merritt <[email protected]>
* term/x11.trm: Remove misleading mention of -noevents. This is a
command line option for gnuplot_x11, not for gnuplot itself.
* src/datafile.c docs/gnuplot.doc demo/heatmaps.dem:
New text input matrix keywords `columnheaders` and `rowheaders`.
These handle reading matrix data from a csv file in which the first
row and/or column contains labels rather than data.
* src/eval.c (update_plot_bounds): Provide a user-visible copy of
the current terminal scale (oversampling, etc) as GPVAL_TERM_SCALE.
Bug #1291
2014-07-28 Allin Cottrell <[email protected]>
* src/syscfg.h: Report 32/64 bit Windows build in version string
2014-07-28 Ethan A Merritt <[email protected]>
* src/wxterminal/gp_cairo.c: Do not pass a linewidth of zero to the
cairo library. The linewidth of LT_AXIS is now set in the core code,
do not further reduce it in gp_cairo_stroke().
2014-07-25 Ethan A Merritt <[email protected]>
* src/gplt_x11.c: Scale x11 dashlength with linewidth.
2014-07-23 Shigeharu Takeno <[email protected]>
* src/mouse.c src/mouse.h src/set.c src/show.c docs/gnuplot.doc:
New command 'set mouse zoomfactors <xfactor>,<yfactor>'
2014-07-22 Ethan A Merritt <[email protected]>
* src/gp_types.h src/plot2d.c (store2d_point):
INRANGE/OUTRANGE refer to points that are inside/outside the plot
boundaries as defined by xrange, yrange, etc. They fail to handle
points that are outside theta range limits given for polar data.
That is, a point may be outside of trange [pi/2:pi] even though it
would lie well inside the plot boundaries if drawn.
Add a new category EXCLUDEDRANGE for such points.
* src/graphics.c (plot_impulses): Test for EXCLUDEDRANGE data points
so that set trange [theta_min:theta_max] actually does something.
Bug #1439
* demo/poldat.dem: Make sure trange includes the whole plot.
2014-07-18 Ethan A Merritt <[email protected]>
* demo/Makefile.am.in: Do not create a symlink to GNUPLOT_X11 in the
build directory during "make check". This was probably intended to
handle the rare case of ./configure --program-suffix=foo but it breaks
the more common case of configuring on a system without x11 support
and then running "make check" twice.
Bugfix
2014-07-14 Ethan A Merritt <[email protected]>
* src/gadgets.c src/save.c src/set.c src/gadgets.h:
Continue to recognize "set style increment user" even though it has
been deprecated in favor of "set linetype".
Bug #1411 (not really a bug)
2014-07-12 Ethan A Merritt <[email protected]>
* src/parse.c (check_for_iteration): Fix failure to detect some loop
[start:end:increment] combinations that should be executed only once
or not executed at all.
Bug #1441
2014-07-10 Ethan A Merritt <[email protected]>
* src/set.c (set_dummy): More sanity checks on "set dummy" syntax.
Bug #1442
2014-07-06 Ethan A Merritt <[email protected]>
* src/set.c (load_tic_user): "set Xtics ()" should clear the list
of user-specified tics rather than setting tic generation to auto.

* docs/gnuplot.doc docs/term-ja.diff docs/gnuplot-ja.doc
man/gnuplot.1 man/gnuplot-ja.1:
Fix typos. Sync Japanese documentation to 1.896
2014-07-04 Bastian Maerkisch <[email protected]>
* src/win/wgraph.c: 'q' closes graph window.
* src/qtterminal/qt_term.cpp (qt_options) term/wxt.trm (wxt_options):
On Windows, the wxt and qt terminals can be used in the same session.
2014-07-01 Ethan A Merritt <[email protected]>
* term/cairo.trm, term/wxt.trm:
Always report {no}enhanced property in "show term".
* src/color.c: If the current terminal has property "monochrome" then
convert all requests for constant color as "black".
Bug #1423
2014-06-24 Ethan A Merritt <[email protected]>
* src/set.c src/show.c src/tables.c docs/gnuplot.doc:
New command: set margins <left>, <right>, <top>, <bottom>
acts just like four successive commands set lmargin <left>, ...
* src/unset.c: unset margins
2014-06-20 Ethan A Merritt <[email protected]>
* configure.in src/wxterminal/wxt_gui.h: The configuration test for
wxWidgets >= 2.8 had no effect on code generation. Remove this test.
* configure.in src/wxterminal/wxt_gui.h: Revert the attemp to guess
whether -lX11 is required by wxt. As feared, this causes problems on OSX
and other platforms where wx is built on top of something other than X11.
2014-06-16 Karl Ratzsch <[email protected]>
* fit.c: FIT_NITER holds number of iterations used by previous fit.
2014-06-16 Ethan A Merritt <[email protected]>
* configure.in src/wxterminal/wxt_gui.h: wxWidgets versions > 2.8 want
the main program to call XInitThreads(), but fail to specify -lX11 in
wxt-config. So we force this ourselves. [=> reverted 2014-06-20]
Bug #1401
* src/graphics.c (xtick2d_callback): Clip r axis tics and tic labels to
the bounding box of the plot.
Bug #1290
2014-06-15 Dmitri A. Sergatskov <[email protected]>
* configure.in: Add LRELEASE for Qt5 autoconfiguration
2014-06-15 Bastian Maerkisch <[email protected]>
* src/plot.c (main): Fix persist mode on Windows when reading
from a pipe.
See Bug #1322
2014-06-15 Akira Kakuto <[email protected]>
* src/binary.c src/datafile.h src/syscfg.h: LFS support on Windows
for MSVC and MinGW.
See also Patch #675
2014-06-14 Ethan A Merritt <[email protected]>
* src/axis.h src/axis.c src/boundary.c src/plot2d.c (eval_plots):
Unlike all other axes, log scaling was being applied to the color axis
(cb) in do_plot() rather than in the caller eval_plots().
This caused "refresh" (as opposed to "replot") to fail. Move the
log-scale correction up to eval_plots() like the other axes.
Bug #1425
* src/misc.c (prepare_call): Allow parenthesized expressions as
call parameters. The value is passed as a string.
* src/command.c (exit_command): New option "exit error 'message'"
prints the message and return to the top command line, breaking out
of any loops or calls cleanly. In non-interactive mode the program
then exits.
2014-06-13 Bastian Maerkisch <[email protected]>
* src/qtterminal/qt_term.cpp (qt_waitforinput): Fix index error
when trying to stop thread which reads from pipe.
Bug #1426
2014-06-13 Ethan A Merritt <[email protected]>
* src/datafile.c (df_generate_pseudodata): Do not try to access plot
structure if we were called from fit rather than plot.
Bug #1427
2014-06-12 Christoph Bersch <[email protected]>
* term/lua.trm term/lua/gnuplot-tikz.lua:
Scale dashlength with linewidth.
2014-06-11 Ethan A Merritt <[email protected]>
* src/mouse.c (event_reset) src/qtterminal/QtGnuplotWindow.{h|cpp}:
Window close events from qt were not being passed through to the main
program, so "pause mouse close" did not work. Also a backgrounded
instance could hang rather than exit when the last plot window closed.
Bug #1418
* src/fit.c: Remove spurious test and error message for time data
with only 2 columns in the using spec.
Bug #1424
* man/gnuplot.1: update
2014-06-11 Mojca Miklavec <[email protected]>

2014-06-11 Tatsuro MATSUOKA <[email protected]>
* win/gnuplot.iss: Include Qt platform DLLs in distribution package.
2014-06-10 Ethan A Merritt <[email protected]>
* docs/gnuplot.doc: Add a section explaining the "persist" option.
Bug #1418, #1419
* term/post.trm term/svg.trm src/qtterminal/qt_term.cpp:
Add an empirical scale factor to the dashlength*linewidth computation to
make the resulting patterns closer in total size to the built-in ones.
2014-06-10 Christoph Bersch <[email protected]>
* term/post.trm term/svg.trm: Scale dashlength with linewidth.
2014-06-09 Daniel J Sebald <[email protected]>
* src/qtterminal/QtGnuplotWidget.cpp (processEvent): Always "resize"
the initial plot to its own size. This may work around strangeness on
some systems that create the initial qt plot window with the wrong size.
Bug #1417 (forwarded from Debian) Patch #661
2014-06-09 Bastian Maerkisch <[email protected]>
* src/win/wgdiplus.cpp src/win/wgraph.c src/win/wgnuplib.h
term/win.trm:
Version 5 dashtypes. Custom dashtypes supported by GDI+ driver.
* src/wxterminal/wxt_gui.cpp: Also "restore" the window state on
"raise".
Bug #1389
* src/win/winmain.c (WinMain): Change type from PASCAL to CALLBACK.
* src/fit.c: Test if covariance matrix is available before saving
it to user variables.

* docs/gnuplot.doc win/README-Windows.txt win/README-ja.txt
docs/gnuplot-ja.doc: sync to docs version 1.891
2014-06-07 Mojca Miklavec <[email protected]>
* src/wxterminal/gp_cairo.c: Scale dashlength with linewidth, similar
to what qt does.
2014-06-04 Bastian Maerkisch <[email protected]>
* src/plot.c src/win/winmain.c|h term/caca.trm: Only if a wxt, caca
or windows terminal window is open, the -persist option is handled by
keeping the main input loop running. This is unfortunate but maybe the
best we can do since we are missing a process fork or detach mechanism.
This avoids a zombie process when no plot windows are open in a
session. For the qt terminal -persist works as on other platforms
since it uses a secondary process.
Bugs #1308, #1335, #1343
2014-06-03 Ethan A Merritt <[email protected]>
* src/graph3d.c src/show.c src/save.c docs/gnuplot.doc:
The hidden3d code processes the lines making up the plot border using
the same algorithm as it does for the plot elements. This renders
partially occluded borders correctly for actual surfaces but fails to
recognize occlusion for, e.g., 3D histograms drawn with impulses.
New keyword option "set border behind" draws the border lines before
the plot elements even for hidden3d plots.
* src/term_api.h src/wxterminal/gp_cairo.c src/wxterminal/wxt_gui.cpp:
Change the implementation of greying out inactive keybox entries in wxt
to use a textbox rather than the active area of the key entry.
Bug #1416
* src/hidden3d.c (draw_vertex): Handle p_type == PT_CHARACTER.
2014-06-02 Bastian Maerkisch <[email protected]>
* src/win/wgraph.c src/win/wgdiplus.cpp:
Grey out key entries when corresponding plot is toggled off.
* src/win/wgraph.c (GraphUpdateWindowPosSize) src/win/wgnuplib.h
term/win.trm (WIN_options): Immediately apply changes to window
position and size.
Bug #1400
* src/datafile.h: Revert the Windows LFS changes for now as
they seem to cause problems on some systems.
2014-06-01 Ethan A Merritt <[email protected]>
* src/axis.c src/gadgets.c src/misc.c src/set.c src/unset.c:
Replace magic numbers with LAYER_{BEHIND|BACK|FRONT}.
* src/graph3d.c: Remove obsolete (always true) conditional
USE_GRID_LAYERS. Minor clean up for the grid layer logic.
2014-06-01 Tatsuro MATSUOKA <[email protected]>
* win/gnuplot.iss: Include gnuplot_qt.exe in installer.
Patch #689
* src/qtterminal/gnuplot_qt.cpp: Search for Qt translation files
in gnuplot's installation directory on Windows.
Patch #687
2014-06-01 Ethan A Merritt <[email protected]>
* src/datafile.h: Partial support for LFS on Windows. Currently
mostly useful for 64 bit builds since integers on the the gnuplot
command line are limited to 31bits otherwise.
Patch #675
2014-06-01 Bastian Maerkisch <[email protected]>
* config/mingw/Makefile: Target 'clean' and 'veryclean' include
Qt files, see patch #688.
* config/mingw/Makefile win/gnuplot.iss: Include RELEASE_NOTES.
Add "qt" as option as default terminal.
2014-05-30 Ethan A Merritt <[email protected]>
* term/post.trm term/cairo.trm: The "header" keyword for epslatex
and related terminals can introduce a string of arbitrary length.
Therefore it is not safe to try to store it in the fixed length
term_options character array.
Bug #1413
* term/gd.trm: Limit the stored length of the font so that term_options
cannot overflow.
Bug #1413
* Makefile.am RELEASE_NOTES: Include Release Notes in the distribution
package.
* FAQ.PDF: Update for version 5.
* src/gplt_x11.c:
Grey out key entries when corresponding plot is toggled off.
2014-05-29 Akira Kakuto <[email protected]>
* term/caca.trm: Modify nominal codepage to accommodate CJK Windows.
2014-05-29 Tatsuro MATSUOKA <[email protected]>
* config/mingw/Makefile: Support compilation of the qt terminal.
Patch #684
2014-05-29 Karl Ratzsch <[email protected]>
* docs/gnuplot.doc: Improve documentation of `update` command.
Patch #686
* src/win/wgdiplus.c src/win/wgraph.c: Change order of pointtypes to
match the sequence in other terminals (cairo, postscript, gd, svg).
Patch #681
2014-05-28 Ethan A Merritt <[email protected]>
* src/graph3d.c (plot3d_points): Handle pointtype PT_CHARACTER.
* src/plot3d.c: Rearrange the order of testing for plot style options
so that it is not possible to end up with uninitialized font or text
properties.
2014-05-27 Ethan A Merritt <[email protected]>
* src/datafile.c (df_readascii): Report status DF_UNDEFINED if a data
value evaluates to the constant "NaN", just as if we calculated it on
the fly to be e.g. 1/0.
* src/stats.c: Remove out-of-date comment that incorrectly describes
what happens in this case.
Bug #1408
2014-05-26 Ethan A Merritt <[email protected]>
* term/js/gnuplot_svg.js term/svg.trm:
Grey out key entries when corresponding plot is toggled off.
* src/qtterminal/QtGnuplotItems.* src/qtterminal/QtGnuplotScene.cpp:
Grey out key entries when corresponding plot is toggled off.
* src/wxterminal/wxt_gui.cpp (wxt_grey_out_key_box):
Grey out key entries when corresponding plot is toggled off.
2014-05-24 Bastian Maerkisch <[email protected]>
* src/wxterminal/wxt_gui.cpp (wxt_waitforinput): Do not wait for an
event when only checking for mouse events.
Bugfix
2014-05-23 Ethan A Merritt <[email protected]>
* src/boundary.c: A width adjustment for the length of the key title
was being applied to every column of entries in the key instead of just
once for the whole key. Apply the "set key {no}enhanced" property to
the key title as well as to the individual plot titles.
Bugfix.
2014-05-19 Ethan A Merritt <[email protected]>
* src/wxterminal/wxt_gui.h: Apparently wxWidgets3 (wxgtk3) threads call
into Xlib but fail to initialize X threading before doing so. Therefore
we must call XInitThreads before forking wxt threads.
Bug #1401
2014-05-19 Karl Ratzsch <[email protected]>
* term/emf.trm: Add point types pentagon (14) and filled pentagon (15)
2014-05-16 Ethan A Merritt <[email protected]>
* src/term.c (load_linetype): As documented, "set linetype cycle N"
should only affect line properties (color, width, dash), not point
properties (type, interval, size). This got lost somewhere, which
meant point types > linetype_recycle_count were never used by default.
Now they are. This means that, as intended, 'with linespoints' cycles
through (linetype_recycle_count * terminal's_max_point_type) distinct
combinations before repeating so long as those two numbers are
mutually prime. Unfortunately that's not guaranteed and is terminal-
dependent. We really need a "set pointtype cycle M" command also so
that you can choose M to be prime relative to N.
Bugfix.
* INSTALL docs/gnuplot.doc: Update description of new features.
2014-05-15 Ethan A Merritt <[email protected]>
* configure.in PATCHLEVEL src/version.c docs/titlepag.tex:
Bump version information to 5.0.rc1
* demo/dashtypes.dem: Avoid irrelevant warning message.
2014-05-14 Karl Ratzsch <[email protected]>
* term/svg.trm src/wxterminal/gp_cairo.c:
Add point types pentagon (14) and filled pentagon (15)
* src/qtterminal/QtGnuplotItems.cpp:
(EAM) Add point types pentagon (14) and filled pentagon (15)
2014-05-13 Ethan A Merritt <[email protected]>
* src/command.c src/tables.c src/tables.h: Remove undocumented routine
test_time(). It was never updated to handle sub-second time precision,
and in any case the functionality is now covered adequately by
"print strptime()" and "print strftime()".
* src/color.c (filled_polygon_3dcoords filled_polygon_zfixed)
src/pm3d.c (filled_color_contour_plot): The option "set pm3d at C" is
undocumented and doesn't work anyhow. Wrap the corresponding code in
#ifdef PM3D_CONTOURS . This disabled code may or may not be useful for
some future implementation of filled contours.
* term/post.trm (PS_dashtype): Always stroke the previous path before
setting a new dashtype.
2014-05-11 Hans-Bernhard Broeker <[email protected]>
* src/util.c (LOCAL_BUFFER_SIZE): New constant.
(gprintf): Use constant to identify buffer size, instead of typing
the same magic number multiple times. Insert warning about
remaining magic number.
* src/plot2d.c (get_data): Fix buffer overflow a bit more cleanly.
(compare_boxplot_factors): Insert warning about magic number.
2014-05-11 Ethan A Merritt <[email protected]>
* src/plot2d.c (get_data): fix buffer overflow
* src/datafile.c (f_stringcolumn): Return an empty string if asked for
stringcolumn(N) on an empty field of a *.csv file. Otherwise it would
return NULL which may cause a segfault later on.
Bugfix.
* src/datafile.c (df_readascii): If xticlabels(f(n)) returns a
non-string value then do not generate an axis tic. It used to issue
a warning about illegal string values but generated a tic anyway.
2014-05-10 Dima Kogan <[email protected]>
* src/mouse.c (do_zoom rescale_around_mouse): Handle various conditions
that caused zooming around the current mouse position to fail.
Re-applied after tracking down conflict.
2014-05-10 Shigeharu Takeno <[email protected]>
* docs/gnuplot.doc: various small corrections
* docs/gnuplot-ja.doc term-ja.diff: Sync translation to version 1.887
2014-05-10 Ethan A Merritt <[email protected]>
* term/gd.trm: Do not allow setting terminal size to 0. Bug #1398
2014-05-10 Hans-Bernhard Broeker <[email protected]>
* term/lua.trm: Ensure initialization of alpha.
* src/hidden3d.c (store_polygon): Ensure initialization of v[],
just in case somebody calls this function with an illegal
'direction' enum value.
* src/win/wgraph.c (PATTERN_BITMAP_LENGTH): Give name to magic number.
(pattern_bitmaps): Use new name.
* term/emf.trm (PATTERN_BITMAP_LENGTH): Give name to magic number.
(pattern_bitmaps): Use new name and make const.
(EMF_filled_polygon): Define pattern pointer more locally and make
it point to const. Use named constant in loop. Fix table
underrun.
* src/win/wgnuplib.c (GetInt): Add some parentheses.
* src/stats.c (statsrequest): Initialize local data structs, to
avoid warnings about printing uninitialized results.
* src/readline.c (BACKSPACE): Define as a character constant, not
some hex number.
(readline): Write TAB as character constant, not some hex number.
* src/interpol.c (gen_interp_frequency): Ensure initialization of
y_total regardless of smooth type.
* src/plot3d.c (grid_nongrid_data): Ensure initialization of
numpoints.
* src/pm3d.c (pm3d_plot): Ensure initialiation of gray.
All the following concern the same problem: Macros from <ctype.h>
cannot safely be called with arguments of type 'char' (because
that may be signed). Such values have to be cast to unsigned char
on passing.
* src/win/wtext.c (TextPutStr): See above.
* term/post.trm (PS_load_fontfile): See above.
* src/win/winmain.c (GetLanguageCode, open_printer): See above.
* src/util.c (streq): See above.

2014-05-08 Dima Kogan <[email protected]>
REVERT patch from 2014-04-26 because it broke normal zoom operations.
* src/mouse.c (do_zoom rescale_around_mouse): Handle various conditions
that caused zooming around the current mouse position to fail.
2014-05-08 Ethan A Merritt <[email protected]>
* src/axis.h (ACTUAL_STORE_WITH_LOG_AND_UPDATE_RANGE)
src/plot2d.c (store2d_point) src/plot3d.c (get_3ddata)
src/datafile.c (df_readascii) src/tabulate.c:
Revised handling of NaN or Inf in the input data stream. The program
used to set type=undefined for this point but left all the data fields
untouched (i.e. left them containing random garbage). Version 5 fills
in all data fields, including the one[s] containing NaN or Inf.
This means that the output from "set table" matches the input data
whereas before any line marked "u" contained garbage in the data fields.
Note: For 3D data z=NaN or z=Inf is replaced by z=0. This is needed to
avoid problems with image data. Possibly this special case should be
handled in the image code itself rather than at the input stage.
* src/plot2d.c (impulse_range_fiddling) src/plot3d.c: Don't extend
range to zero for log-scaled axes.
2014-05-06 Ethan A Merritt <[email protected]>
* term/emf.trm: Custom dashtype support.
* configure.in term/pdf.trm: Modify PDFlib terminal for use with
version 5 dashtypes (but no custom dashtype support). Do not build
by default.
2014-05-05 Ethan A Merritt <[email protected]>
* src/gp_types.h src/graphics.c (place_objects do_rectangle)
src/misc.c (lp_parse) src/save.c (save_object) src/set.c (set_obj):
Allow object borders to have a full set of line properties including
dashtype.
* docs/gnuplot.doc: Update documentation to better describe recent
changes.
* src/qtterminal/QtGnuplotScene.cpp: Always use a solid line to draw
point symbols, even if the current linetype has a dash pattern.
* term/cairo.trm term/canvas.trm term/post.trm term/svg.trm term/wxt.trm
term/x11.trm src/term.c: Terminals that have been upgraded to version 5
dash handling should ignore the "dashed/solid" terminal setting.
* src/plot2d.c (impulse_range_fiddling) src/plot3d.c: Autoscaled plots
"with impulses" should include y=0 (z=0 in 3D) unless log-scaled.
2014-05-05 Tatsuro MATSUOKA <[email protected]>

2014-05-01 Hans-Bernhard Broeker <[email protected]>
* config/mingw/Makefile (LDFLAGS2): Add auto-import flag.
($(TARGET)): Add icon files and Makefile as dependencies.
* config/config.mgw, config/config.cyg: The set of used /
available configuration macros has changed across the past several
years.
* src/stdfn.h (sgn): Fix parenthesization of macro.
(PATH_MAX): CLang compiler on Cygwin needs a silly little tweak.
* src/graphics.c (samesign): Improve parenthesization a bit.
2014-05-01 Ethan A Merritt <[email protected]>
* demo/gantt.dem demo/html/*: Add Gantt chart to demo collection.
Add dashtypes to demo collection.
* src/show.c: Show "fixed" property of arrow style.
2014-04-29 Ethan A Merritt <[email protected]>
* src/datafile.c (f_timecolumn): Replace the old 1-parameter function
timecolumn(col) with a 2-parameter timecolumn(col,"timeformat"). The
old version had no way to handle time data that didn't correspond to
a coordinate on a plot axis in time format (e.g. set xdata time).
It would segfault if the function appeared in a using spec slot >= 2.
Now we require an explicit format, so data input is dissociated from
any particular axis or time setting.
Bug #1394
* src/gplt_x11.c term/x11.trm term/xlib.trm:
Custom dashtype support for X11.
2014-04-28 Dima Kogan <[email protected]>
* src/mouse.c src/mouse.h src/set.c src/show.c docs/gnuplot.doc:
Remove the distinction between "coordinate format echoed to the screen
during mousing" and "coordinate format saved to the clipboard on click".
This removes the default bindings for hotkeys 3 and 4.
2014-04-28 Shigeharu Takeno <[email protected]>

* src/graphics.c (plot_steps): Avoid overflow in clipping code.
==> Reverted in favor of fixing the clipping code itself.
* src/gadgets.c (clip_line): It is not safe to use (A*B >= 0) as a
substitute for the test (sign(A) != sign(B)).
It fails when A and B are integers and their product overflows.
Bugs #1390, #1392 See also Bug #1358
* src/stdfn.h: Define a sgn() function.
* src/graphics.c: Use sgn() function to define samesign().

2014-04-26 Dima Kogan <[email protected]>
* src/mouse.c (do_zoom rescale_around_mouse): Handle various conditions
that caused zooming around the current mouse position to fail.
Bug #1380
[REVERTED 2013-05-08 because it broke normal zoom]
2014-04-25 Ethan A Merritt <[email protected]>
* src/misc.c (lp_parse): Disallow defining "set lt N lt M".
This used to mean "define effective linetype N to be the hidden device
specific linetype M", except that in other contexts it meant "use
effective linetype M rather than effective linetype N". Version 5
distinguishes between color and dashpatten, so require an explicit
command to set one or both rather than an ambiguous old-style request.
* src/save.c (save_pm3dcolor save_linetype): Save special linetypes
by keyword rather than a magic number (e.g. lt bgnd rather than -3).

* src/gp_types.h src/misc.c (lp_parse) src/misc.h src/plot2d.c

Bug #1387
2014-04-24 Dima Kogan <[email protected]>
* src/mouse.c (do_zoom_scroll_up): Fix typo that causes incorrect

2014-04-23 Ethan A Merritt <[email protected]>
* src/command.c src/graph3d.* src/set.c src/show.c src/save.c
docs/gnuplot.doc: Introduce a scale parameter "set view map {scale}"
and set the default size of a plot in this mode to approximately the
same as a default 2D plot.
* src/command.c (replotrequest): It's now OK to have a range in a
replot command, since it can be applied to the new plot piece only.
* src/datafile.c (df_readascii): If a read request returns a string
rather than a numerical value, nevertheless fill in the numerical
value as NaN. This is better than leaving some random garbage there
(in practice probably some earlier data value).
Bugfix.

* src/mouse.c (event_buttonpress): Flip direction of horizontal
scrolling to match the convention used by vertical scrolling.
2014-04-14 Ethan A Merritt <[email protected]>
* configure.in (AC_FUNC_FSEEKO) src/datafile.h: LFS support part 2.
If possible, use fseeko/ftello to navigate input data files.

* configure.in (AC_CHECK_TYPES([off_t])) src/syscfg.h (#define off_t)
src/binary.c src/datafile.c src/datafile.h: Change the declared type
of all variables contributing to calculation of file offsets from (int)
to (off_t). This is sufficient to allow seeking in files > 2GB on 64bit
platforms. It may also allow LFS support on some 32bit platforms if
compiled with -D_FILE_OFFSET_BITS=64 but in general it will also be
necessary to replace fseek/ftell with fseeko/ftello (32bit linux) or
_fseeki64/_ftelli64 (MSVC).
2014-04-11 Ethan A Merritt <[email protected]>
* src/datafile.c (df_binary_details[]): Handle int64 and uint64 types
even if current platform has sizeof(long) = 4.
Bugfix
2014-04-08 Ethan A Merritt <[email protected]>
* src/save.c (save_linetype) src/misc.c (lp_parse)
src/graphics.c (plot_lines) src/graph3d.c (do_3dplot plot3d_lines)
src/boundary.c (do_key_sample):
New linetype keyword "nodraw" maps to existing internal value LT_NODRAW.
Apply this in the graphics layer rather than the terminal layer in order
to distinguish between line properties and point properties.
I.e. this draws blue points but no lines:
plot $FOO with linespoints lt nodraw pointtype 6 lc rgb "blue"
* src/term.c (term_apply_lp_properties): Distinguish between l_type
values that really indicate a linetype (e.g. LT_NODRAW, LT_AXIS) and
those which indicate a dash pattern. Send the former directly to
term->linetype(). Send the latter to term->dashtype(), which may itself
call term->linetype() if there is no private implementation of dashes.
2014-04-07 Ethan A Merritt <[email protected]>
* src/term.c (null_dashtype): Ignore custom dashtypes. Pass through
dashtypes > 0 to term->linetype(). Treat negative dashtypes as LT_BLACK.
This should allow terminals without a private dashtype implementation to
continue working as they did before (pre-version 5).
* src/plot2d.c (eval_plots): Don't call lp_parse if all we want is
a fill color.
* src/boundary.c (do_key_sample) src/graphics.c (plot_boxes plot_c_bars):
Funnel requests for linetype changes through term_apply_lp_properties().
* demo/all.dem: Add varcolor.dem to the test set.
2014-04-06 Christoph Bersch <[email protected]>
* src/graphics.c (fill_between): It is no longer necessary to clip in
this routine because the component quadrilaterals will be clipped later.
2014-04-05 Ethan A Merritt <[email protected]>
* src/set.c (set_table): Name leak.
2014-04-05 Bastian Maerkisch <[email protected]>
* demo/vector.dem docs/gnuplot.doc src/command.c src/datablock.c
src/datablock.h src/gadgets.c src/gadgets.h src/plot2d.c src/set.c
src/tabulate.c src/tabulate.h src/unset.c src/util.c src/util.h:
'set table $datablock' redirects table output to a named data block.
Patch #662
2014-04-04 Ethan A Merritt <[email protected]>
* src/term.c (load_linetype): If a line style is based on a lt < 0
(LT_NODRAW, LT_BACKGROUND, LT_BLACK, etc), take only the line color.
FIXME: LT_AXIS should also take the dash pattern but that mechanism
isn't fully in place yet.
Bug #1369
* src/util.c (value_to_str): Fix error in buffer length accounting.
Bug #1372
