LinearScale Class

Assembly: DevExpress.Xpf.Gauges.v20.2.dll

NuGet Packages: DevExpress.WindowsDesktop.Wpf.Gauges, DevExpress.Wpf.Gauges

Declaration

C#
VB.NET

public class LinearScale :
    Scale

Public Class LinearScale
    Inherits Scale

The following members return LinearScale objects:

Remarks

This scale is used with the LinearGaugeControl. It is represented by an instance of the LinearScale class. It can be accessed as an item of the LinearScaleCollection object returned by the LinearGaugeControl.Scales property.

A Linear Scale consists of tickmarks, labels, custom labels, ranges, layers. It also uses the following value indicators: a level bar, markers and range bars.

A typical Linear Scale is shown in the image below:

Linear Gauge_Scale

Example

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