Axis2D.VisualRange Property

Gets or sets the settings that specify the visible range of the axis coordinates.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v23.2.dll

NuGet Package: DevExpress.Wpf.Charts

Declaration

C#

public Range VisualRange { get; set; }

VB.NET

Public Property VisualRange As Range

Property Value

Type	Description
Range	A Range object which contains the common visual range settings of the axis coordinates.

Remarks

The VisualRange property is used in descendants of the AxisBase class. The primary settings exposed via the properties of the Range class allow you to specify, for example, the minimum and maximum axis values (see the Range.MinValue and Range.MaxValue properties).

Examples

The following markup shows how to specify visual and whole ranges:

XAML

<!--...-->
<dxc:XYDiagram2D.AxisX>
    <dxc:AxisX2D>
        <dxc:AxisX2D.WholeRange>
            <dxc:Range MinValue="05/24/2016" 
                       MaxValue="08/25/2016"/>
        </dxc:AxisX2D.WholeRange>
        <dxc:AxisX2D.VisualRange>
            <dxc:Range MinValue="06/18/2016" 
                       MaxValue="07/03/2016"/>
        </dxc:AxisX2D.VisualRange>
    </dxc:AxisX2D>
</dxc:XYDiagram2D.AxisX>
<!--...-->

The markup above uses the following classes and properties:

Class or Property	Description
Axis.WholeRange	Gets or sets the axis whole range’s settings.
Axis2D.VisualRange	Gets or sets the axis visual range’s settings.
Range	The axis range.
Range.MinValue	The range’s minimum limit.
Range.MaxValue	The range’s maximum limit.

You can call the Range.SetMinMaxValues method to limit a range at runtime. The following code customizes an x-axis’s visual range:

C#

using DevExpress.Xpf.Charts;

private void Window_Loaded(object sender, RoutedEventArgs e) {
    Range visualRange = ((XYDiagram2D)chartControl1.Diagram).ActualAxisX.ActualVisualRange;
    visualRange.SetMinMaxValues(minValue: new DateTime(2019, 4, 1), maxValue: new DateTime(2019, 10, 1));
}

VB.NET

Imports DevExpress.Xpf.Charts

Private Sub Window_Loaded(ByVal sender As Object, ByVal e As RoutedEventArgs)
    Dim visualRange As Range = CType(chartControl1.Diagram, XYDiagram2D).ActualAxisX.ActualVisualRange
    visualRange.SetMinMaxValues(minValue:=New DateTime(2019, 4, 1), maxValue:=New DateTime(2019, 10, 1))
End Sub
