Chart3DControl.ShowCrosshair(Point, Boolean) Method

Shows the Crosshair Cursor at the point with the specified coordinates. The autoHide parameter specifies whether the Crosshair Cursor is automatically hidden.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v23.2.dll

NuGet Package: DevExpress.Wpf.Charts

Declaration

C#

public void ShowCrosshair(
    Point screenPoint,
    bool autoHide
)

VB.NET

Public Sub ShowCrosshair(
    screenPoint As Point,
    autoHide As Boolean
)

Parameters

Name	Type	Description
screenPoint	Point	The Crosshair Cursor coordinates relative to the 3D chart’s top-left corner.
autoHide	Boolean	true, if the Crosshair Cursor is hidden for a point that was removed and added again; otherwise, false

Remarks

The following example shows the Crosshair Cursor on the MouseUp event:

C#

private void Chart_MouseUp(object sender, MouseButtonEventArgs e) {
  Chart3DControl chart = (Chart3DControl)sender;
  Point point = e.GetPosition(chart);
  chart.ShowCrosshair(point,false);
}

VB.NET

Private Sub Chart_MouseUp(ByVal sender As Object, ByVal e As MouseButtonEventArgs)
  Dim chart As Chart3DControl = CType(sender, Chart3DControl)
  Dim point As Point = e.GetPosition(chart)
  chart.ShowCrosshair(point, False)
End Sub

When a data point under the Crosshair Cursor is removed at runtime, the Crosshair Cursor is hidden. Set the autoHide parameter to false to show the Crosshair Cursor when this data point appears again in the same position.

You can use the HideCrosshair method to hide the Crosshair Cursor.
