DrawOptions Class

Represents a class that contains settings for custom drawing series of different view types.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v21.1.dll

Declaration

public class DrawOptions :
    ICloneable

The following members accept/return DrawOptions objects:

Remarks

Instances of the DrawOptions class are passed to the ChartControl.CustomDrawSeries and ChartControl.CustomDrawSeriesPoint events, and can be accessed via the CustomDrawSeriesEventArgs.DrawOptions property. In these event handlers, you can change specific appearance settings of a series by customizing the DrawOptions.Color property of the DrawOptions class.

Example

This example shows how to change the color of each series point according to its values.

In addition, the point labels text is changed to show the color of the current interval (Green, Yellow, or Red).

To accomplish this, it is necessary to invoke the ChartControl.CustomDrawSeriesPoint event and change its drawing options in the CorrectDrawOptions() method.

In this example, you can deactivate the “Custom Draw” option on the stack panel to return to the default appearance of series points.
