How to: Color TreeMap Using the Palette Colorizer

To color all group items using one color, set the TreeMapPaletteColorizer.ColorizeGroups property of the colorizer to true. To specify a palette that should be used to color items, assign an instance of the Palette derived class to the TreeMapPaletteColorizerBase.Palette property of the colorizer.
