[opendx-users] coloring elevation

[Steve Legowik]

I am still new to OpenDX and I am having trouble figuring out how to 
get my data to display the way I want.  Please bear with my possibly 
ignorant inquiries.

What I have is a scattering of points in 3D.  I want to display the 
points as glyphs colored base on the elevation, the z coordinate of 
the point position.  But I can't figure out how to access the 
locations z coordinate since it is a position and not one of the 
'fields'.
