Changes

Some preliminary modules were contributed by After Peter Münster posted the first module for gnuplut support on the mailing list [http://article.gmane.org/gmane.comp.tex.context/24884] and (which only works with bash), Hans Hagen (see [http://article.gmane.org/gmane.comp.tex.context/24935] [http://article.gmane.org/gmane.comp.tex.context/24965] on the mailing list to enable inclusion ) wrote another one and Taco additionally provided some bugfixes and minor changes. The module is now a part of gnuplot graphs from ConTeXt. Follow the links mentioned above to see official distribution, but may undergo some other minor changes in the detailsshort term (use with care for some time). General idea is to enable gnuplot graphics inclusion with simple commands such as:

set terminal postscript eps mp colorset title 'Trigonometry'solid

plot sin(x)

\useGNUPLOTgraphic[sin][width=5cm]

=== More complex example with MetaPost === Metapost produces the plots of a relatively high quality. You can use TeX commands to format the title, label axes and legend. <texcode>\usemodule[gnuplot] % output may be "mp/metapost", "ps/postscript", "pdf" or "png"; ps is currently the default\setupGNUPLOT[output=mp,option=color] % general settings for the whole document\startGNUPLOTinclusions  # you may use TeX commands to format the titles and axes set title '\bf Trigonometry'Note set xlabel '$x$' set ylabel '$y$'  # to prevent uneven numbering: Peterwill result in # (0.0, 0.5, 1.0, 1.5, ...) instead of # (0, 0.5, 1, 1.5, ...) set format yaxis '\%.1f'\stopGNUPLOTinclusions \startGNUPLOTgraphics{tan} plot tan(x) t '$\tan(x)$'\stopGNUPLOTgraphics \startGNUPLOTgraphics{sin} plot 4*sin(x)+x t '$4\sin(x)+x$', x t '$x$' lt 3\stopGNUPLOTgraphics \useGNUPLOTgraphic[tan]\useGNUPLOTgraphic[sin][width=10cm]</texcode> There's module currently only works under one problem that you have to be careful about: [[MetaPost]] terminal uses <code>cmr</code> fonts for labels. If you have the stand-alone distributions, you either have to install them by yourself or to play with <code>set terminal mp {fontname}</code> a bit (http://www.gnuplot.info/docs/gnuplot.html#mp). === More complex example: Multiple terminals === You can use different terminals for plotting the same function. {{todo|an example, similar to the one in [[source:m-gnuplot.tex|m-gnuplot.tex]], some images to get a visual impression of the main differences in terminals}} == Requirements == You have to have Gnuplot installed (and in your PATH). On most Linux, Hans's module has problems installations this is probably already the case. On Windows you either need to put the gnuplot binary in PATH manually or to create a file <code>pgnuplot.bat</code> with newlines "C:\Program Files\gnuplot\wgnupl32. Hoping exe" %1 %2 %3 %4 %5 %6 %7 %8 %9and put that that will file to a <i>"visible place"</i> (has to be fixed found in PATH). For most terminals you need <b>texmfstart</b>(.exe) as well.In case you don''t have it yet, you can grab it [http://www.pragma-ade.com/context/current/cont-win.zip here]. [[write18]] has to be enabled as well.
