LinearScaleRangeCollection Class

A collection that stores the ranges of a particular linear scale.

Namespace: DevExpress.Xpf.Gauges

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

NuGet Package: DevExpress.Wpf.Gauges

Declaration

C#

public class LinearScaleRangeCollection :
    LayerCollection<LinearScaleRange>

VB.NET

Public Class LinearScaleRangeCollection
    Inherits LayerCollection(Of LinearScaleRange)

Related API Members

The following members return LinearScaleRangeCollection objects:

• LinearScale.Ranges

Remarks

Each linear scale can hold a collection of ranges returned by the LinearScale.Ranges property and represented by the LinearScaleRangeCollection class. Each collection item is an instance of the LinearScaleRange class and can be accessed via the GaugeDependencyObjectCollectionBase<T>.Item property of a LinearScaleRangeCollection object.

For more information on ranges, refer to the Range (Linear Scale) document.

Example

This example illustrates how to create a LinearGaugeControl instance with two LinearScale objects.
