I'm afraid you cannot create ScalarMaps to PointSize. But
you can pass ConstantMaps to DisplayImpl.addReference().
To change point size for a Data object, pass its DataReference
to DisplayImpl.removeReference() then pass it to
DisplayImpl.addReference() with a new ConstantMap to
PointSize.
Good luck,
Bill
