Re: [slightly OT] plotting a (pm3d) closed surface with arbitrary vertices

Hans-Bernhard,

Thanks!
This was indeed what I was looking for and it works already pretty well.
What I'd need now, is to invalidate the data outside some distance to
the data points. Suppose I've data whithin a banana shape in x, y and
like to have colored pm3d rectangles only when x, y are near the banana
(which is defined by the scatter x, y data points).
Maybe you've a quick solution for this problem as well? ;-)
