I personally refuse to do any work until Dave finishes the book and makes it
available.

What's this... talk of an object graphics book on the horizon? How do I
add my name to the waiting list? I've been thinking of delving into
object graphics and I am wondering where the best place to begin is? I
notice that RSI has some books on object graphics but nobody ever refers
to them (Advanced Application Development in Object Graphics and
Object-Oriented Programming and Graphics in IDL). Are they worth their
price? What other manuals, for object graphics are available? Any words
of wisdom?

Multiple plots in object graphics are a great deal more
flexible than multiple plots in direct graphics using
!P.Multi, since you are not confined to a regular grid.
You can literally put plots anywhere on the display (or
off, alas!) that you like.
Create as many viewports as you need. Add them all to
a scene, and render the scene in your destination object.
Each viewport can be mapped to a different location
in the destination object.
Probably the reason you don't see too many examples of
this is that it is awkward to write the code that accepts
(in a general way) all of the data and all of the keywords
for all of the plots you wish to generate. But, if *you*
know all that information ahead of time, it is not difficult.

Well, thanks is good, but a willingness to part with money is
even better! :-)
Maybe I'll get back to the book. My attempts to get back
on the Tennis Tour suffered a setback again last weekend
when that young pup, 30 years younger than me, ran me
all over the court until my knees gave up. I'd take up
golf, but Ernie Els and David Duval tell me that's pretty
much hopeless for the next 30 years too, what with Tiger around. :-(
