Hello Daniel,
In general, triangulation algorithms implemented with double precision arithmetic are not stable with certain kinds of input, especially ordered sets of points like the ones that you are displaying. In other words, sometimes the
surface series simply fails to triangulate the points that you specify. You can configure the chart to use geometric calculations with adaptive precision - this will make the triangulation somewhat slower, but more robust. To enable this feature, you have to set the UsePreciseGeometry property to true.
By the way, the occurrence of this problem is often a sign that the triangulated
surface might not be appropriate. You can display the same
surface with the Mesh
Surface series - no issues with the precision and it renders much faster.
