Chart3DHitInfo Class

Contains information about a specific point within a chart.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v24.2.dll

NuGet Package: DevExpress.Wpf.Charts

#Declaration

public class Chart3DHitInfo :
    ChartHitInfoBase

The following members return Chart3DHitInfo objects:

#Remarks

Chart3DHitInfo objects can be created by calling the chart’s Chart3DControl.CalcHitInfo method. This method requires the test point as a parameter, or its coordinates.

The Chart3DHitInfo class properties can be grouped into two categories:

  • The properties that indicate whether the test point resides over a particular view element. For instance, the ChartHitInfoBase.InAxis property indicates whether the test point is over the axis;
  • The properties identifying the topmost visual element, which contains the test point (e.g., ChartHitInfoBase.Axis).

#Example

This example shows coordinates for a surface point and series point marker clicked in a 3D chart:

using DevExpress.Xpf.Charts;
using System.Windows;
//...
private void Chart3DControl_MouseUp(object sender, System.Windows.Input.MouseButtonEventArgs e) {
    Chart3DHitInfo hitInfo = chart.CalcHitInfo(e.GetPosition(this));
    if (hitInfo.InSeries) {
        string str;
        if (hitInfo.SeriesPoint != null) {
            SeriesPoint3D point = hitInfo.SeriesPoint;
            str = $"X: {point.NumericXArgument:f2}, Y: {point.NumericYArgument:f2}, Z: {point.Value:f2}";
            MessageBox.Show(str);
        }
        if (hitInfo.AdditionalItem != null) {
            SurfacePoint surfacePoint = (SurfacePoint)hitInfo.AdditionalItem;
            str = $"X: {surfacePoint.X:f2}, Y: {surfacePoint.Y:f2}, Z: {surfacePoint.Z:f2}";
            MessageBox.Show(str);
        }
    }
}
