Warning: getting offtopic. Furter question are better directed to
comp.text.tex
Tip 1: use single letter labels in IDL: this makes it a lot easier to
generate the substitution text. Also ensure that you use hardware fonts
(say, times) in your plot. Numbers along the axis can be a bit more
painful, although if you ensure that the values are scaled to a range
where exponents are not needed, you'll probably be just fine (just add
the scale factor to the axis label).
Tip 2: The following latex file may help:
\documentclass{article}
\usepackage{geometry}
\usepackage{graphicx}
\usepackage{psfrag}
\pagestyle{empty}
\geometry{paperwidth=12cm,paperheight=8cm,margin=0pt}
\begin{document}
% define labels here
\includegraphics[width=12cm,height=8cm]{figure.eps}
\end{document}
Adapt sizes to your liking, make sure the lines you use in IDL are
thick enough.
Process with
latex
and
dvips -o figure-labeled.eps figure.dvi
This should produce a ps file with width 12 cm and height 8 cm. Convert
to pdf ans used with pdflatex as you please, although I think the ps
outout can be included with latex+dvips as well (despite teh fact that
it isn't eps). The -E flag may be interesting for dvips as well.
