AxisCoordinate.Axis Property

Specifies an axis to which the annotation anchor point’s coordinate corresponds.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v21.1.dll

NuGet Package: DevExpress.Wpf.Charts

Declaration

C#

public object Axis { get; set; }

VB.NET

Public Property Axis As Object

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.

MainWindow.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>
