The option {\tt createstyle} is used to create three files with required macros in working directory\footnote{An alternative is to place those three files somewhere where kpathsea can find them and omit the option {\tt createstyle}, just make sure that the versions of {\tt tikz} terminal and the files in your \TeX\ tree remain compatible.} + +Both terminals should give you almost equivalent results apart from default plot size. You are highly encouraged to specify the disired plot size explicitely. You may scale the plot later on, but you probably want to get the desired proportions from the start. + +Run gnuplot with +\startbackground +gnuplot example.plt +\stopbackground +and compile the result with any of the following three commands (depending on your preferred engine): +\startbackground +\hbox{\hbox to 25em{context fullpage-example.tex \hss} {\rm\# for \LuaTeX}} +\hbox{\hbox to 25em{texexec fullpage-example.tex \hss} {\rm\# for \pdfTeX}} +\hbox{\hbox to 25em{texexec --xtx fullpage-example.tex \hss} {\rm\# for \XeTeX} } +\stopbackground + +They are almost equivalent except that \XeTeX\ lacks some advanced features (some patterns). The only major difference is the choice of fonts. If you want to typeset Arabic labels or use system fonts, you will probably want to choose \LuaTeX\ or \XeTeX. If you are using many graphical elements (like in 3D plots), you might want to go for \LuaTeX. + +You should get a {\sc pdf} document with two full-page plots that you can include into your document with \type{\externalfigure[fullpage-example][page=2]} for example. + +\placefigure[force]{}{\externalfigure[fullpage-example][page=2]} + + +\subsection{Calling gnuplot from \TeX} + +As you can see you will always get Latin Modern font at 12pt unless you explicitely change it with {\tt header "\textbackslash setupbodyfont[...]"}.
