3  * For gnuplot version 5.4
4  * pgf.REVISION = "114"
5    Force linewidth to 0pt for text node justification
6  * pgf.REVISION = "113"
7    pgf.REVISION_DATE = "2020/06/02 16:02:00"
8    revise gppoint to pass through opacity information
9    keep old variant gppoint so that old files still work
10    new variant is called gp3point  (3 parameters rather than 2)

13
14  * support for ConTeXt and plain TeX
15  * removed dependencies for LaTeX packages other than TikZ
16  * needs TikZ Version >= 2.0
17  * better support for saving terminal options with gnuplot 'save' command
18  * all bitmap images can be externalized
19  * alpha channel support for bimap images via externalized PNGs
20  * new options 'crop', 'background', 'textscale', 'externalimages'
21  * fixed "overflow" bug on negative coordinates that are outside of the crop box
22  * various small bugfixes
23
24  Backward compatibility is dropped again.
25

27
28  * Providing a script or target name is now mandatory. The new syntax:
29       set terminal lua <target name> | "<file name>"
30                        {<script_args> ...}
31    This will look for a script named `gnuplot-<target name>.lua' or
32    a script named "<file name>" (in quotes!).
33  * Support for script names via the environmental variable
34    GNUPLOT_LUA_SCRIPT is dropped.
35  * The option "script" is obsolete and also removed.
36  * Via the environmental variable GNUPLOT_DRIVER_DIR the default search
37    directory for driver scripts can be changed.
38  * The TikZ driver help is now included as a subsection of the Lua
39    terminal.
40  * minor bugfixes (see ChangeLog)
41
42  This version drops backward compatibility again!
43
442008-12-20
45
46  * Removed all underscrores in style and color names.
47  * The plot box coordinates are now accessible via a special node. (e.g.
48    "gp plot 1.north east".
49  * Added aliases 'standalone' ('fulldoc') and 'header' ('preamble')
50  * Preparations to echo back the options string to the user.
51
52  This version drops backward compatibility!
53
542008-11-22
55
56  * Changed default canvas size to 12.5cm x 8.75cm and use the preview
57    package to clip the plot in 'fulldoc' mode (suggested by Juergen Wieferink).
58  * New option 'charsize'. In conjunction with the gnuplottex.sty the
59    font size can now be determined automatically. (look at the style file for
60    example code).
61  * Removed the default font setting (previously set to "\small").
62
63  No binary updates needed.
64
652008-02-02
66
67  * Implemented a mapping of gnuplot arrow styles to TikZ arrow styles by
68    "misusing" the angle of the gnuplot arrow definition.
69  * CMYK support for image data (all other colors are handled through the
70    xcolor package).
71  * terminal works with gnuplottex (\begin{gnuplot}[terminal=lua]...)
72    (http://www.ctan.org/tex-archive/help/Catalogue/entries/gnuplottex.html)
73  * compatibility updates for gnuplot 4.3cvs version
74  * optional environment variable GNUPLOT_LUA_SCRIPT
75  * fixed zero length paths artifacts and some more minor bugs
76  * added simple pager functionality for help output
77
78  The Lua script should work with the previous binary version, but the new
79  GNUPLOT_LUA_SCRIPT feature and pager functionality will not be available.
80  Maybe a minor issue for most users ;-)
81
822007-10-03
83
84  * New option 'providevars' to make gnuplot's internal and user variables
85    available within the TeX-script.
86  * Adopted the color scheme and dash patterns to (largely) resemble the
87    look of the postscript terminal.
88  * Changed the names of the bounding box coordinates from 'lowerleft' to
89    'south west' etc. to be closer to the TikZ naming scheme.
90
91  Binary update needed on upgrade.
92
932007-09-22
94
95  * Lengths in the 'size' options now accept the units cm, mm, in or inch, pt,
96    pc, bp, dd and cc.
97  * Switched from generic TikZ styles like 'every plot' to gnuplot specific
98    TikZ-styles.
99  * Support for plotting images of pixel and binary 2D-data. For PDF and
100    Postscript generation the image will be included in a native PDF or PS
101    format what reduces space and compile time and improves rendering quality.
102    For the SVG output of PGF/TikZ the 'native image' feature has to be
103    disabled manually. The image will then be rendered of filled rectangles.
104  * Added 'tikzplot' option which allows using the TikZ '\path plot'
105    command instead of the simple '\path' for plots with given linetypes.
106  * Added 'is_multiplot()' to the Lua terminal (currently unused in the
107    TikZ backend).
108  * Changed the Lua-API: Color and fill styles are now passed as strings
109    instead of integers to the script.
110
111  Binary update needed on upgrade.
112

114
115  * Improved robustness of the option parser.
116  * Fixed a PGF/TikZ compatibility issue reported by Scott Murman.
117
118  No binary update from previous version needed.
119
120
1212007-08-25
122
123  * Fixed rectangle scaling in conjunction with the 'plotsize' option
124    (thanks to Scott Murman for reporting).
125
126  This update only affects the gnuplot.lua script.
127
128
1292007-08-24
130
131  * A 'size' option for the canvas was added.
132  * The 'scale' option now expects an x and y parameter, so the
133    'xscale' and 'yscale' options where removed. Scaling and resizing
134    now work similar to the other terminals.
135  * The 'monochrome' and 'solid' options do not change the actual
136    TikZ plot commands anymore, but only change the according TikZ
137    style settings.
