Math & Science ⇒ I want my gnuplot code INSIDE my LaTeX document!

[ludachrispeed]

And I have found a way to do that with the gnuplottex package, but I can't figure out how to make it produce graphs with color. Here is a minimal working example of what I have:

Code: Select all

\documentclass{article}

\usepackage{gnuplottex}

\begin{document}

\begin{gnuplot}
  set key left
  plot [-2:2] x,x**2
\end{gnuplot}

\end{document}

This can be compiled with pdflatex --shell-escape foo.tex. You need to use shell-escape so that latex can call gnuplot.

Does anyone know of a way I can get the graph to have color?

This manual should come handy:

Thank you very much for the link. I tried some and eventually got a gnuplot error

terminal "latex" does not support continuous colors.

I've heard there's a way to do it with PSTricks. I'll keep a lookout.

I found a solution to this!

Simply set the terminal type to epslatex. This creates an eps, which is automatically included in the latex file.

Here's a MWE:

Code: Select all

\documentclass{article}

\usepackage{gnuplottex}

\begin{document}

\begin{gnuplot}
  set terminal epslatex color
  set title 'Color graphs with gnuplottex'
  set key left
  plot [0:3*pi][-2:2] sin(x), cos(x)
\end{gnuplot}

\end{document}

compile with latex --shell-escape foo.tex. This of course makes a .dvi file, which can be converted to postscript using dvips, which can then be converted to pdf using ps2pdf.
