Remarks

Use the CrosshairEnabled property to activate (deactivate) the crosshair cursor at the level of a ChartControl. Use the SeriesBase.CrosshairEnabled and Indicator.CrosshairEnabled properties to enable (disable) the crosshair cursor for specific series and indicators.

To customize the crosshair cursor appearance and position options, use the ChartControl.CrosshairOptions property.

The following image shows the enabled crosshair cursor with the CrosshairOptions.ShowArgumentLabels, CrosshairOptions.ShowValueLabels, CrosshairOptions.ShowArgumentLine and CrosshairOptions.ShowValueLine set to true.

To customize the crosshair cursor label content, use the SeriesBase.CrosshairLabelPattern property for series and the Indicator.CrosshairLabelPattern property — for indicators.
