> What are the minimum and maximum values of your coordinate data?

The range for the data is small, nanometer sizes. My data files
represent the coordinates for atom positions in a crystal lattice.
The precision in the coordinates goes out to 15 or so decimal places,
for ex: 4.271762465783982 nm.

I see how the example works with Integers, but I need to find what
"color" would be for each row of data (floating point). I think the
"MOD" function may pose a problem here, although I've not played
around with it yet.
