I’m trying to draw a mesh surface, with draw flat, zone colouring, with using empty data point when data is not available for them. Take an example of a “grid” of 3 by 3. If all 9 point have data the surface the countour map is draw perfect. If I remove data for the middle points in the outter lines, the surface is draw incorrectly, sometimes with nothing being draw at all.
