Namespace: DevExpress.Xpf.Gauges

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

Declaration

public class ArcScaleLayer :
    ScaleLayerBase
Public Class ArcScaleLayer
    Inherits ScaleLayerBase

Remarks

A layer specifies the appearance of the circular scale's elements. It is represented by ArcScaleLayer object contained in the ArcScaleLayerCollection object, which can be accessed via the ArcScale.Layers property.

When a new layer is added to the circular scale, it is painted behind all other elements, because by default, its LayerOptions.ZIndex is less than other elements. If you want to display layers in front of scale elements, set their Zindex to a greater value.

The following image illustrates this layer's appearance.
