Problem with TriSurface series in TeeChart Active X Control

[Marjan]

When I tried to display the data on the TeeChart control object in the dialog, the program gave me a response "Similar Points, can not execute". What is problem behind this?

The internal Voronoi algorithm tries to construct vertices for triangles. And if some points are too close or at wrong position (for the algorithm) then internal routine will not be able to construct triangles and report this back to user. To recap: the "problem" is in data you're trying to plot. The Voronoi algorithm is quite good in constructing surfaces, but sometimes it still fails.
