Can anyone point me to an example or user manual information on how to draw two circles on a 2d mesh surface. I have found information on how to intercept the OnAfterPaint callback but after that I am a bit stuck.

Thanks Richard

Hello Richard,

You can take a look at the following examples in our Windows Forms demo application:

All Examples > Custom Painting > ...
All Examples > Coordinate Transformations > Scale to Viewport

There is also a topic about custom painting in the documentation:

Chart for .NET > User's Guide > Miscellaneous > Custom Painting
