it may depend on the fonts that you use (I'm still working in Hershey
age), but I usually find I get better results producing a postscript
plot and then use xv (which is installed almost everywhere and should be
installed everywhere ;-) to take a screen-snapshot from ghostscript. xv
can then save gif, tiff, xpm, bmp, jpeg, etc.
Of course you need a biiiig monitor for this ;-)

Ah, then it is even easier. All you have to learn is one
Image_Write command, not 4-5 separate commands. :-)
Cheers,
David
P.S. It might take you a couple of hours to write the PV-Wave
equivalent of XWindow. But all the pieces are available.

David,
I'm using PV-Wave version 6, not IDL (I assume they are not the same). Will
your suggestion still work for PV-Wave? I'm not trying to output a picture,
I'm trying to electronically save a plot: "plot,x,y". It's actually more
complicated than just using the plot command, though. Thanks for the reply.
Steve
