How to: Dock an Annotation to a Pane

Jun 07, 2019

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.
MainWindow.xaml

xaml

<dxc:Annotation.AnchorPoint>
    <dxc:PaneAnchorPoint Pane="{Binding ElementName=defaultPane}">
        <dxc:PaneAnchorPoint.AxisXCoordinate>
            <dxc:AxisXCoordinate Axis="{Binding ElementName=xAxis}" 
                                 AxisValue="2.85"/>
        </dxc:PaneAnchorPoint.AxisXCoordinate>
        <dxc:PaneAnchorPoint.AxisYCoordinate>
            <dxc:AxisYCoordinate Axis="{Binding ElementName=yAxis}" 
                                 AxisValue="-30"/>
        </dxc:PaneAnchorPoint.AxisYCoordinate>
    </dxc:PaneAnchorPoint>
</dxc:Annotation.AnchorPoint>
