LinearScaleLabelOptions Class

Contains behavior, layout and data representation options for linear scale labels.

Namespace: DevExpress.Xpf.Gauges

Assembly: DevExpress.Xpf.Gauges.v24.1.dll

NuGet Package: DevExpress.Wpf.Gauges

Declaration

public class LinearScaleLabelOptions :
    ScaleLabelOptions

The following members return LinearScaleLabelOptions objects:

Remarks

The options provided by a LinearScaleLabelOptions instance can be accessed via the LinearScale.LabelOptions property of a LinearScale object.

To define the behavior of the linear scale labels, use the ScaleLabelOptions.ShowFirst and ScaleLabelOptions.ShowLast properties.

The label’s layout is specified by the LinearScaleLabelOptions.Orientation, ScaleLabelOptions.Offset and ScaleLabelOptions.ZIndex properties.

To customize how data is represented on scale labels, use the ScaleLabelOptions.Addend, ScaleLabelOptions.Multiplier and ScaleLabelOptions.FormatString properties.

For more information on labels, refer to the Labels (Linear Scale) document.

Example

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