Don't pass your time_set to the ShapeControl. You need a ScalarMap
of some RealType to Display.Shape. Values of this RealType will
define indices into the array of shapes you pass to the setShapes()
method of your ShapeControl, quantized according to the SimpleSet
you pass to setShapeSet(). Remember to call setShapeSet() before
you call setShapes().
If you want a cube at each point, pass 'new Integer1DSet(1)' to
setShapeSet(), then construct a cube as in visad/examples/Test47.java
and pass it in a singleton array to setShapes(). You can map 'x'
to Shape, since the Integer1DSet(1) with one member means that 'x'
values are ignored.
Good luck,
Bill
