public class DigitalGaugeLayer : GaugeLayerBase
Public Class DigitalGaugeLayer Inherits GaugeLayerBase
A layer specifies the appearance of the digital gauge's elements. It is represented by the DigitalGaugeLayer object contained in the DigitalGaugeLayerCollection object, which can be accessed via the DigitalGaugeControl.Layers property.
When a new layer is added to a digital gauge, it is painted behind all other elements, because, by default, its LayerOptions.ZIndex is less than other elements. If you want to display gauge layers in front of other scale elements, set their Zindex to a greater value.
The following image illustrates this layer's appearance.
