Oh, I don't doubt your figures at all. I just think it
is a shame, given how easy objects are to use (and I am
*not* talking about object graphics now) and how
significantly they could change the way your write
programs.
But I'm old enough to remember how we had to bring
all you old farts, uh, excuse me, scientific programmers,
along with widgets, too, so I still hold out hope. :-)
Cheers,
David

That proves it.
I'm a nobody... on both fronts! :-(

When I do my "I"nterative "D"ata analyses, I don't use objects or
widgets. What would be the point? PLOT is your best friend. For me
the most important thing is ease of use at the interactive command
line; then, once I have a nice plot, I plop it into a script (or use
XFWINDOW) and I can reliably come back to it later. Monkeying around
with axis objects seems like it would be a pain. And from what I hear
the object graphics printed output is pretty crappy [at least up until
now.] That doesn't seem like a good trade...
So, for the interactive command line user, which would you recommend
David?

So, that brings back my request: a new improved Help/tutotial,
comprehensible filled with USEFUL examples that will help us to get started.
As I began with IDL i focused to object grafics, but soon i found it took me
far too much code to do what i could do with a couple of lines of direct
grafics.
Now i use object grafics to do intercative 3D renderings by modifying the
surf_track procedure for my own needs. But unfortunatedly i found the code
to complex (for the little time i have to study it) to begin writing my own
object grafics applications. Sure a good tutrial/help would come handy.
Thanks
Luis =)

Well I do. But I must admit that it's been more work than I expected. As
someone used to say, "If you want to reduce a scientist's productivity give
him/her a computer." (Well actually they used to say "him".)
BTW Joe, I thought you said in your original contribution on this subject
you were going to send all replies to /dev/null.
