<FONT face=Arial color=#0000ff
size=2>on my laptop AB has about 56 colors. I tried it and
color management was hopeless, you cannot gradually change the shade of a
color to show that you are going up/down a peak/slope. Another inconvenience
is that you have to make a color translation table, since the numerical
sequence of colors will not be the best one for 3D maps.

<FONT face=Arial color=#0000ff

indicate slope and we cannot rotate the image. So the visual effect must
entirely be accomplished with shading colors. You could undoubtedly create a
simple heatmap, but 3D, hmmm not good enough for
me.

program. It takes me about 5 seconds to copy the results to Excel and make 3D
maps there. Once there I have a whole array of maps and options to chose
from...

Re: 3D contour PlotHerman,If you go to
Preferences->Colors->Palette editor you may define 16 shades
of a color in the custom colors area. Aren't they enough to give a
