Namespace: DevExpress.Xpf.Charts
Assembly: DevExpress.Xpf.Charts.v24.2.dll

#Declaration
#Property Value
Type | Description |
---|---|
Object | An object of an axis’s View Model class or the Axis2D object. |
#Remarks
When the Annotation.AnchorPoint property is specified as PaneAnchorPoint, define a particular pane using the PaneAnchorPoint.Pane property. Use the PaneAnchorPoint.AxisXCoordinate and PaneAnchorPoint.AxisYCoordinate properties to configure the anchor point’s x- and y-coordinates. Then, set the AxisCoordinate.Axis
and AxisCoordinate.AxisValue properties for each axis coordinate.
#Example
This example shows how to anchor an annotation to a pane.
- Specify the PaneAnchorPoint.Pane property to define a pane to which the annotation should be anchored.
Define the axes and their values to specify the annotation’s anchor point. To do this, use the PaneAnchorPoint.AxisXCoordinate and PaneAnchorPoint.AxisYCoordinate properties.
If the PaneAnchorPoint.Pane and
AxisCoordinate.Axis
properties are unspecified, the default pane and primary axes are used to display the annotation. You can leave the Pane and Axis properties undefined if you plot the annotation on the default pane with primary axes.
