ScaleLabelOptions.ShowFirst Property

Gets or sets a value indicating whether or not the first label should be shown on a scale.

Namespace: DevExpress.UI.Xaml.Gauges

Assembly: DevExpress.UI.Xaml.Gauges.v18.2.dll

Declaration

public bool ShowFirst { get; set; }
Public Property ShowFirst As Boolean

Property Value

Type Description
Boolean

true to display the first label on a scale; otherwise false.

Use the ShowFirst and ScaleLabelOptions.ShowLast properties to show or hide the first and last labels on a scale. This may be required, for example, when these labels are both displayed at the same position and the resulting gauge looks ugly. In this case, you can hide the first label by setting the ShowFirst property to false.

For more information on labels, refer to labels (Circular scale) and labels (Linear scale) documents.

Examples

The following example demonstrates how to create a Circular Gauge with two needles, three ranges, one marker and one range bar.
