Public Class IndicatorPoint
The following members return IndicatorPoint objects:
You can use the IndicatorPoint class members to show information about an individual indicator point using the Crosshair Cursor.
This example shows how to modify the Crosshair Cursor indicator elements’ appearance using the CustomDrawCrosshair event.
In this sample, crosshair content is displayed in a legend. For this, set the ContentShowMode property to Legend. Note that you can specify the crosshair’s content show mode for a specified indicator using the CrosshairContentShowMode property.
Use the IndicatorLegendElements property to obtain a collection of indicator elements.
The following properties allow you to modify indicator element appearance:
| Property | Description |
|---|---|
| IndicatorPoint | Returns information about an indicator point under a crosshair. |
| CrosshairLegendElementBase.LineElement | Returns the crosshair line settings. |
| CrosshairLegendElementBase.AxisLabelElement | Returns the crosshair axis label settings. |
