Thanks for the info, but in looking at your code, it appears that it
would assign case 1 as one color and case 2 as another color, correct?
If so, what I need to do is create a grid that has a color range. Let
us say the values are between 1 and 5, so that value one is purple and
value two is red and all values in between are a gradation between the
extremes. Of course this is a simple case and I will probably have
values a couple orders in magnitude in range and will need to be able
to "auto bin" them. Will this code work for that, or do I need
something else?
Thanks,
~Matt
