Remarks

This class introduces the TreeMapGroupGradientColorizer.GradientColor that allows specifying the mixing color, and the TreeMapGroupGradientColorizer.Min and TreeMapGroupGradientColorizer.Max properties specifying the maximum and minimum of portion of the color assigned to the item’s group.

For more information about colorizers, refer to the Colorizers topic.

Example

To color each tree map group using similar colors, use the TreeMapGroupGradientColorizer class. Assign an instance of the class to the TreeMapControl.Colorizer property. The TreeMapPaletteColorizerBase.Palette property specifies colors assigned to groups. The TreeMapGroupGradientColorizer.Max and TreeMapGroupGradientColorizer.Min properties configure the maximum and minimum portion of palette colors in colors assigned to items. The TreeMapGroupGradientColorizer.GradientColor property sets a color with which palette colors are mixed.
