Hi everyone :)

I want to use this program to view roughly 100 regularly spaced points,
and their properties. The problem I seem to have is that the ORBS are
not spherical, but instead kind of ellipsoid. This is because the data
ranges for X, Y and Z are not comparable? What I mean is that the
xrange goes from 0-100, while the zrange from 0-0.01 for example. Any
idea on how to fix this? ( Im relatively new to IDL ;) )

The program can be found here:
http://www.dfanning.com/tip_examples/scatter_surface.pro

And I think the orbs are created in this section:

; Create the symbols for each point. This is almost certainly
; not the most efficient way if you have lots of points, but
; it works well for a reasonable number.

npts = N_Elements(x)
orbs=ObjArr(npts)
line=ObjArr(npts)
FOR j=0,npts-1 DO BEGIN
orbs[j] = Obj_New('ORB', Color=[r[zcolors[j]], g[zcolors[j]],
b[zcolors[j]]], $
Style=2, Radius=0.015, Pos=[x[j],y[j],z[j]])
line[j] = Obj_New('IDLgrPolyLine', [x[j], x[j]], [y[j], y[j]],
[min(z), z[j]], $
Color=[r[zcolors[j]], g[zcolors[j]], b[zcolors[j]]])
thisModel->Add, orbs[j]
thisModel->Add, line[j]
ENDFOR

Also, my data consists of 3 different sets. I would like to have 1
color for each set, but ofcourse different when compared to the other
2. Any hints on how to proceed on this?

Thanks in advance! :)
