x-y plotting utility

[Larry Thorne]

We're looking for an xy plotting utility that's more versatile than the
standard graph/plot stuff.  It should be able to display under sunview and
it would be nice if it could produce postscript and/or HPGL output.  The
ability to enter multiple datasets is needed, along with labeling
capabilities (x-y axis, labels for each curve, etc.).  Color isn't
necessary, but...

I've tried gnuplot (nice, but no multiple datasets per plot) and I'm
looking at vplot (seems to be a programming language), but I need a simple
utility that users can feed data into and get plots in their sunview
windows and/or to the postscript laserwriter.

Thanks in advance for any pointers or suggestions!  I'll post the results
if needed.
