To use the Range Colorizer, perform the following steps.

• Create a RangeColorizer object and assign it to the Series.Colorizer property.
• Populate the RangeColorizer.RangeStops collection.
• Specify the ChartPaletteColorizerBase.Palette property if you want to use a non-default palette to colorize a chart.
• In addition, it is possible to specify the RangeColorizer.ValueProvider property to customize the way you used to provide floating point number values based on color data member values.
