Create a FlatField with MathType (index -> (x, y, r, g, b)),
create r[], g[] and b[] arrays of colors for your 200 points,
pass 'new float[][] {x, y, r, g, b}' to the setSamples()
method of your FlatField, and display with ScalarMaps x -> XAxis,
y -> YAxis, r -> Red, g -> Green and b -> Blue.

Good luck,
Bill
