How to: Color Tree Map Using the Group Gradient Colorizer

• Jun 07, 2019

To color tree map items using the Group Gradient Colorizer, do the following.

• Assign a newly created TreeMapGroupGradientColorizer object to the TreeMapControl.Colorizer property.
• Specify the required palette using the TreeMapPaletteColorizerBase.Palette property, and the gradient color using TreeMapGroupGradientColorizer.GradientColor.
• Optionally, set the TreeMapGroupGradientColorizer.Min and TreeMapGroupGradientColorizer.Max properties to required values.
