Assembly:  System.Windows.Forms.DataVisualization (in System.Windows.Forms.DataVisualization.dll)

public virtual DataPoint AnchorDataPoint { get; set; }

Property Value

Type: System.Windows.Forms.DataVisualization.Charting.DataPoint

A DataPoint object to which an annotation is anchored.

The annotation is anchored to the X and Y values of the specified data point, and automatically uses the same axes coordinates as the data point.

To automatically position the annotation relative to the anchor point, make sure its X and Y properties are set to NaN. The AnchorAlignment property can be used to change the automatic position alignment of the annotation to the anchor point. The AnchorOffsetX and AnchorOffsetY properties may be used to add extra spacing.

When you use this property, make sure the AnchorX and AnchorY properties are set to Double.NaN, as they have precedence.

Set this value to null to disable annotation anchoring to a data point.
