Namespace: DevExpress.Xpf.Charts

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

NuGet Package: DevExpress.Wpf.Charts

Declaration

C#

public bool? CrosshairEnabled { get; set; }

VB.NET

Public Property CrosshairEnabled As Boolean?

Property Value

Type	Description
Nullable<Boolean>	Null - a crosshair cursor’s state (enabled/disabled) is automatically determined based on the type of diagram currently displayed on a chart; True - a crosshair cursor is enabled for a chart; False - a crosshair cursor is disabled.

Remarks

Use the CrosshairEnabled property to activate (deactivate) a crosshair cursor at the level of a ChartControl.

After that, it becomes possible to customize a crosshair cursor’s appearance and position on a diagram via the ChartControl.CrosshairOptions property.

You can also change the content of a crosshair label, via the XYSeries2D.CrosshairLabelPattern property and crosshair label appearance using the XYSeries2D.CrosshairLabelTemplate property.

The following table shows this property in action.

CrosshairEnabled=True	CrosshairEnabled=False

Note

The CrosshairOptionsBase.ShowCrosshairLabels and CrosshairOptions.ShowArgumentLine properties are enabled by default.

To show series point markers on a diagram, set the MarkerVisible property for a particular series to true (e.g., LineSeries2D.MarkerVisible).
