The data was displayed as contours in the source application, so that appears not to be a problem. > 2.

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).
