You can do it with only one DataReference, if you
use your UnionSet as the domain Set of a FlatField.
For example, if your UnionSet has MathType:

  Set(x, y)

Then use it as the domain Set of a FlatField:

  ((x, y) -> (r, g, b))

and set values in r, g and b to color each point. Use the
same color for the points in the same Gridded2DSet, and
different colors for different Gridded2DSets.

This sounds like the usual Swing layout troubles. I usually
use nested BoxLayouts, as in visad/benjamin/Galaxy.java.
But lots of folks on this list know more than me about Swing.

Good luck,
