SeriesSeriesPointsAction.EqualSpeed Property

Gets or sets a value that specifies whether to provide equal animation speed for each series point in 3D charts.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v18.2.dll

Declaration

C#

public bool EqualSpeed { get; set; }

VB.NET

Public Property EqualSpeed As Boolean

Property Value

Type	Description
Boolean	true, if the speed of series points animation is equal; otherwise, false.

Remarks

For more information, see Animation.

Example

The following example demonstrates how to animate series points, so that their values are dynamically changed when displaying a chart.

To accomplish this, it is first necessary to add a trigger to a chart’s Triggers collection, which will start the Year1998Animation in response to the chart’s Loaded event. Then, to the ChartControl.AnimationRecords collection, add a ChartAnimationRecord with a SeriesAnimation object.
