Hello all,
I've been trying to make a very simple 3D graph for days now and I'm
completely stumped because I know nothing about this. My data is
gridded data of temperatures at different levels of the atmosphere
over Antarctica and I have nice plots using map_set and contour for
each level separately but I would really like to have a 3D version of
just one temperature contour throughout the entire atmosphere. Is
there a way to get a z-axis added to a map and contour at each level?
I've tried using T3D but I'm not understanding how it applies to
contour and plot or really how it works at all. I've also tried to
use the isosurface, scale3 and then polyshade to view a certain
temperature surface but I keep running into this error: POLYSHADE:
Vertex 0: X,Y,Z location out of range. which I dont know how to fix.
Is there an easy way to do this or am I way off track?
Thanks,
Stephanie

Oh, dear. Well, don't worry about it. You are doing
direct graphics. Don't even *attempt* object graphics
unless you have Ronn Kling's book, IDL Power Graphics,
right next to you. :-)
Cheers,
David
