Ah, well, one always hopes it works with the example data. :-)

Now, with *real* data you begin to appreciate the complexities
of object graphics. I'd guess that the radius of the orbs is
going to be tied, somehow, to the data range. If you use
a data range dissimilar to the one I used in the
example, it is possible that the orb shrinks to such a small
size you can't see it, or to such a large size that you are
inside it. In either case, you are probably hosed.

Just for kicks, I'd change the ORB radius in Scatter_Surface
and hope you see something with your data. The BIG problem with
object graphics is that *everything* is possible, including all
those things that are dumb, stupid, or just plain useless.
Change it by at least an order of magnitude or so. If you change
it enough, we might begin to get a clue to what is going on.

Cheers,

David
