Devon, That's a good start; it seems easier than it did earlier. And it's a cool, easy algorithm; I learned something. I'm going to have to play around with it a bit ... getting the RGB numbers for the colors I want, and then assembling a palette I think will do the job to see if it works. What I wonder about is if I can change the palette so as to have the effect of changing the underlying algorithm. 'surface' & plot has the effect of varying color by z direction. That's fine, but I want to change the color according to the x (or maybe y) direction, not the z direction. I'm content to have the color either stay the same or vary in intensity as the z coordinate varies, but I need three bands in the x direction to be in the green family and the next four to be in the brown family (there are only 7 bands of x data in this data). For any one value of x and z, the color shouldn't change as y varies. I'll explore more later.
