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.

MainWindow.xaml

<dxtm:TreeMapControl.Colorizer>
    <dxtm:TreeMapGroupGradientColorizer 
        GradientColor="White"
        Min="0.5"
        Max="1">
        <dxtm:Office2013Palette/>
    </dxtm:TreeMapGroupGradientColorizer>
</dxtm:TreeMapControl.Colorizer>
