The data was displayed as contours in the source application, so that
appears not to be a problem.

That was it. Changing to a 2-D domain with manifold dimension = 2 (as
you described in a separate message, quoted below) fixed it, and I may
even understand why. :)
To get a true 2-D domain, call the Gridded2DSet constructor
signature with 4 arguments, the last two being X and Y lengths
(their product should be the single length you are passing now).
