Use the locations of the interpolated points to construct a
Gridded2DSet with manifold dimension = 1. You can see an
example of this constructor in visad/examples/Rivers.java
(which then combines several such Gridded2DSets into a
UnionSet to get several lines, but you don't need that step).
Good luck,
Bill
