You know, I bet you really want a different grid from the one you have. Consider this positions-dependent grid:
(Embedded image moved to file: pic09171.pcx) If you Post it, you get this: (Embedded image moved to file: pic26268.pcx) But maybe you really wanted this: (Embedded image moved to file: pic28261.pcx) That is, cells centered at the data points, rather than with vertices at the data points.

But still, for completeness, how can I take the corner values of the vertices instead of the average. This is what I prefer, since then you can see the real values as they appear in you data set, without any modification. Thanks for the tip anyway.
