I have for some time intended to make something similar to what
mathurl (http://mathurl.com/) does. But so far never had the time to
do it. The hard part would be handle the external dependency on LaTeX
in a reasonably tolerable and platform-independent way. Maybe with
JLaTeXMath through an IDL_Java bridge.
Ideally the LaTeX output should be vectorial, not bitmap. But drawing
the vectors might also be tricky, depending on how they are provided.

If you want anything more then basic stuff, do use psfrag.
That will allow you to put any LaTeX formula into your plot.
IDL own symbols are very limited.
Ciao,

Thank you,
PSFrag looks interesting - not a package I have come across, but seems
to do the job. I think you are on to something with a mathurl type
system - I would certainly rather write the whole string in Latex
format and just include the output image as the title say, so the
spacing etc. is correct. As you say however, scaling bitmaps is
obviously less than ideal unless you can tie the latex fontsize to the
charsize tag in IDL?
Again, thanks for the prompt replies
