Append pages to existing Postscript file with gnuplot

Question

I want to save some plots that I obtain from different gnuplot programs, ran at different time to go on to the same postscript. At present, if I set the terminal to postscript and give an output file like this:

set terminal postscript eps size 19.2,10.80 enhanced color \
    font 'Helvetica,20' linewidth 2
set output 'temp.eps'

gnuplot overrrides the existing file "temp.eps" and plots the new plot in a new file. How can I make it to append another page to the existing postscript?

Gnuplot cannot merge postscript files. Possibly you can find some command line tool to which you can pipe the output which then merges the current plot with previous ones, like set output "| mytool old.ps -". — Christoph

You can use latex to do this. The following tex file (which I have named test.tex) will embed your eps files (here temp.eps and temp2.eps) into the same PS file:

\documentclass{article}

\usepackage{graphicx}

\begin{document}

\centering
\includegraphics[width=0.9\textwidth]{temp}

\newpage

\centering
\includegraphics[width=0.9\textwidth]{temp2}

\end{document}

For which you need to run

latex test.tex
dvips test.dvi

which generates a PS document called test.ps which contains temp.eps in the first page and temp2.eps in the second page.
