Re: Do you have a sample java code on how to plot x,y?

See visad/examples/  It displays a data object
(a FlatField named histogram1) with MathType
  (ir_radiance -> count)
that is displayed according to the ScalarMaps:
  ir_radiance -> XAxis
  count -> YAxis
  count -> Green
The also has four simple
x, y plots in its display2.

A MathType may be a primitive type, or may be a composite type
built up from primitive types.  So in, ir_radiance
and count are primitive types (in VisAD, they are called RealTypes
or TextTypes) and thus also MathTypes, and (ir_radiance -> count) 
is a composite MathType but not a primitive type.
