First of all, I don't know about iPlot. I've never used
it. It is not so much a limitation of object graphics,
as one of its strengths. You can do *everything* in
object graphics, if you are willing to spend months
figuring out how to do it.
I'd give MPI_PLOT a go. It is easy to overplot with that,
and you get most of the supposed "advantages" of iPlot,
without the god awful complexity.

P.S. I'll be talking about how to build this *exact*
application (in about 20 minutes!) at the IDL Users
Group meeting on Thursday. This will correspond, roughly,
with the release of my Catalyst Library as an Open Source
software project. I'm thinking this might well result in
iTool-like programs that even somebody like me can program. :-)
