ChartHitInfo.SeriesPoint Property

Gets a series point which is located under the test point.

Namespace: DevExpress.Xpf.Charts

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


public SeriesPoint SeriesPoint { get; }
Public ReadOnly Property SeriesPoint As SeriesPoint

Property Value

Type Description

A SeriesPoint object, specifying the series point located under the test point.


Use the SeriesPoint property to access the series point located under the test point (if the ChartHitInfo.InSeries property returns true).

And, if ChartHitInfo.InSeries is false, the SeriesPoint property returns null (Nothing in Visual Basic).


This example demonstrates how to calculate the hit information for the chart element over which the mouse pointer is hovering.

To accomplish this, handle the ChartControl.MouseMove event, obtain the current chart element via the ChartControl.CalcHitInfo method, and if the element is not null (Nothing in Visual Basic), display its information.

            StringBuilder builder = new StringBuilder();

            // Check  whether the chart element is under the test point and if so - obtain the element's content.
