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.v19.2.dll

Declaration

C#

public bool ShowFirst { get; set; }

VB.NET

Public Property ShowFirst As Boolean

Property Value

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

Property Paths

You can access this nested property as listed below:

Object Type	Path to ShowFirst
ArcScale	.LabelOptions.ShowFirst
LinearScale	.LabelOptions.ShowFirst

Remarks

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.

Example

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