</dxc:Series3D>

Example 2

The following example shows how to calculate point colors based on point x-arguments.

• Create a class that implements the IColorizer3DValueProvider interface.
• Implement its IColorizer3DValueProvider.GetValue method.
• Assign the class instance to the RangeColorizer3D.ValueProvider property.
