Example

This example demonstrates how to use the RangeSegmentColorizer to color a line series by its segments.

Follow the steps below to configure the RangeSegmentColorizer object and apply it to a line series view:

Create a RangeSegmentColorizer instance and assign it to the LineSeriesView.SegmentColorizer property.
Populate the RangeSegmentColorizer.RangeStops collection.
Use the RangeSegmentColorizer.Palette property to define a palette.
The RangeSegmentColorizer.LegendItemPattern property allows you to specify how to format text the legend shows for each color range.
