Re: Displaying 3D data as 2D + color ?

I posted a question on this a while back and I never got a really good answer, it
seems mathematica was not designed for extreme ease in plotting data  points that
are scattered.  I believe I ended up doing it with Hue[z/maxz*.9].  The .9 is
because with Hue[z], both z=0 and z=1 are red.  I'm currently running to the same
problem with contours, my max and min heights are red if I want color, or I can
remain in grayscale.
