Hi Daya,

The control comes with tens of examples of surface charts - we support grid, mesh and triangulated surface types. The first step is to determine the type of surface you actually need - the following links in the documentation explain the differences:
http://helpdotnetvision.nevron.com/#UsersGuide_ChartTypes_Surface_Grid_Surface.html
http://helpdotnetvision.nevron.com/#UsersGuide_ChartTypes_Surface_Mesh_Surface.html
http://helpdotnetvision.nevron.com/#UsersGuide_ChartTypes_Surface_Triangulated_Surface.html

After you choose the surface type you can locate the appropriate examples. To do so launch the WinForms example project and check the surface examples located at:
All Examples \ Chart Gallery \ Grid Surface
All Examples \ Chart Gallery \ Mesh Surface
All Examples \ Chart Gallery \ Triangulated Surface

Hope this helps - let us know if you meet any problems or have any questions.

Best Regards,
Nevron Support Team
