[Tex/LaTex] Creating colorful plot using latex terminal of gnuplot

colorgnuplotpdftex

Most output terminals of gnuplot draw different lines in a plot in different colors.

I'm trying to create a plot inside my PDF document using gnuplot's LaTeX terminal and the lines are only distinguishable by linestyle.

What do I need to do to get the lines colored?

I use pdflatex.

From this example:

\documentclass{scrreprt}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage[miktex]{gnuplottex}
\usepackage{graphicx}

\begin{document}
\begin{figure}[htbp]
\centering
\begin{gnuplot}[terminal=latex]
plot [0:2*pi] sin(x) title 'Sine', cos(x) title 'Cosine'
\end{gnuplot}
\end{figure}

\end{document}

I get this result:

@texenthusiast provides part of the solution: set the options [terminal=epslatex,terminaloptions=color] when using gnuplot.

And don't forget to load epstopdf in your preamble:

\usepackage{epstopdf}

The lines in the plot will now be colored but still have different styles.

To give them the same style you can now use something like

set style line 1 linecolor rgb '#0060ad' linetype 1 linewidth 2
set style line 2 linecolor rgb '#dd181f' linetype 1 linewidth 2
plot [0:2*pi] sin(x) with lines ls 1 title 'Sine', cos(x) with lines ls 2 title 'Cosine'

Best Answer

Out of the many( latex, tex, epslatex,pstricks pdf and lua/tikz) gnuplot terminal exports available epslatex seems reasonable.

Using [terminal=epslatex,terminaloptions=color] seems to be optimal since .eps plot is taken from gnuplot and TeX is used to typeset text in labels/titles to give nice consistency. But for more options gnuplottex might give details. 

\documentclass{scrreprt}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage[miktex]{gnuplottex} % for MiKTeX,`pdflatex -shell-escape` enabled 
%\usepackage{gnuplottex} I have used this line to compile on TeXLive 2013
\usepackage{graphicx}
%\usepackage{epstopdf} % for MiKTeX,`pdflatex -shell-escape` enabled
\begin{document}
\begin{figure}[htbp]
\centering
\begin{gnuplot}[terminal=epslatex,terminaloptions=color]
plot [0:2*pi] sin(x) title 'Sine', cos(x) title 'Cosine'
\end{gnuplot}
\end{figure}
\end{document}
