Or maybe GRAFFER (README below). If you walk 3 doors down the corridor,
Craig, I'll show you my copy.

GRAFFER
Author: James Tappin (sjt@star.sr.bham.ac.uk)
Version 1.03 -- January 1996
GRAFFER is an X-Y plot generating package written in IDL. It needs a
workstation or terminal supporting IDL widgets and at least version 4.0
of IDL.
The approach of GRAFFER is an essentially pragmatic one. It aimed to
fill the gap between the kind of simple plots that are trivial to do in
IDL just by using the plotting procedures from the IDL> prompt and the
sort of complex and specialised plots where it's worthwhile to write a
specific program.
The main features are:
* Can plot X-Y data with optional error bars (only vertical bars at
present): from a file, or from a simple text-widget editor, or from
arrays accessible at the $MAIN$ level in IDL.
* Can plot functions: y=f(x), x=f(y) or x=f(t) & y=g(t).
* Easy to change axis ranges, switch between log & linear plots and
other XSTYLE & YSTYLE options.
* Add text at arbitrary locations, orientations, fonts etc.
* Can put multiple plots on one set of axes - with different colours,
linestyles symbols etc. to distinguish them.
* Saves plots to an ASCII file which can be re-read & modified.
* Print to PostScript or save to EPS with customizable size &
orientation. (Also GIF, TIFF & NRIF dumps available).
GRAFFER has been tested on a Sparc 5 running Solaris 2.4 - it ought to
work on other unix systems and on VMS. Windows & Mac I'm much less
certain about -- all I can suggest is try it & see.
Usage:
GRAFFER may be freely used, copied & distributed but please:
1) Don't claim you wrote it.
2) If you change it make it clear which bit you've changed and don't
say I made the changes.
3) Let me know of you improvements.
Warranty: NONE - You didn't pay any money so you take your chance if
it's useful: GOOD, if it isn't you got what you paid for.
Maintenance: I'll try to fix bugs, but don't expect any new features.
