Graphics, Figures & Tables ⇒ tikz - gnuplot integration

[CoolnessItself]

Using the following code:

Code: Select all

\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw[color=blue] plot[id=sin] function{sin(x)} node[right] {$f(x)  = \sin x$};
\end{tikzpicture}
\end{document}

compiled with
--shell-escape --enable-write18

I don't get a plot, only the text. My log file has lines
runsystem(gnuplot test.sin.gnuplot)...executed.
Package pgf Warning: Plot data file `test.sin.table' not found. on input line 7

So it sounds like gnuplot makes a .gnuplot file and pgf is looking for a .table file (right?). If I rename test.sin.gnuplot to test.sin.table and recompile, I get
! Package PGF Math Error: Unknown function `set'.

I've tried editing line 288 of
C:\Program Files (x86)\MiKTeX 2.8\tex\generic\pgf\modules\pgfmoduleplot.code.tex from
set terminal table
to
set table
as some threads have suggested, same result.
gnuplot is in my %PATH%.


Any suggestions?

For MiKTeX use only the latter one.

Quite logical. Gnuplot actually should generate a *.table file so that renaming is not necessary. But this file is only generated if the terminal is set correctly in the *.gnuplot file that is generated by pgf/tikZ (or pgfplots).

This patch is only needed for Gnuplot 4.4.0 and higher. Its functionality seems to be proved.

Please clarify which version of Gnuplot you are using.

For the present you may use the internal plot mechanism of the package. For details see the package manual.

    \draw[color=blue] plot (\x,{sin(\x r)}) node[right] {$f(x) = \sin x$};
