PointBasedSegmentColorizer Class

The colorizer that uses the point marker colors to paint line/area segments.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v20.1.dll

Declaration

public class PointBasedSegmentColorizer :
    SegmentColorizerBase,
    IPointSegmentColorizer
Public Class PointBasedSegmentColorizer
    Inherits SegmentColorizerBase
    Implements IPointSegmentColorizer

Remarks

You can apply the Point Based Segment colorizer to the line/area series and their descendants. To do this, assign the PointBasedSegmentColorizer object to the series's SegmentColorizer property.

The SeriesPoint.Color property specifies the point marker and its adjacent segment's color. You can define SeriesPoint.Brush directly or use a point colorizer.

The PointBasedSegmentColorizer class introduces the PointBasedSegmentColorizer.Direction property to specify the direction that is used to distribute the point marker color.

Examples

This example demonstrates how to use the PointBasedSegmentColorizer to paint a line series by its segments.
