Namespace: DevExpress.Xpf.Gauges
Assembly: DevExpress.Xpf.Gauges.v18.2.dll
Declaration
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 |
|
LinearScale |
|
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.
The table bellow illustrates the properties behavior.
ShowFirst=True, ShowLast=True | ShowFirst=False, ShowLast=True | ShowFirst=True, ShowLast=False |
---|---|---|
For more information on labels, refer to labels (Circular scale) and labels (Linear scale) documents.
Example
This example illustrates how to create a CircularGaugeControl instance with a single ArcScale object.
