TreeMapGroupGradientColorizer Class
The colorizer that colors the tree map items in colors blended from group colors and gradient colors in a proportion based on the tree map item value.
Namespace: DevExpress.Xpf.TreeMap
Assembly: DevExpress.Xpf.TreeMap.v19.1.dll
Declaration
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.
Example
To color tree map items using the Group Gradient Colorizer, do the following.
- Assign a newly created
TreeMapGroupGradientColorizerobject 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.
