Labels Overview

Labels overview

The gauge labels are visual elements displaying numeric values at a specified interval on the scale.

Label Properties and Events

Label properties and events summary

The following table summarizes the UltraRadialGauge control’s label properties.

Property Name Property Type Description

Double

Determines the label position as a value between 0 and 1 from the center of the gauge with 0 placing the labels at the center of the gauge and 1 placing the labels on the radius of the gauge.

Double

Determines the interval to use for rendering labels; by default this is the same interval as the tick marks on the scale.

The following table summarizes the UltraRadialGauge control’s label related events.

Event Name Description

This event is raised when aligning a gauge label along the scale

This event is raised when formatting a gauge label

Configuring the Label

Example

The following screenshot illustrates how the UltraRadialGauge control renders with the label’s properties configured like this:

The following is the code for implementing this example

In C#:

var radialGauge = new UltraRadialGauge();
radialGauge.LabelExtent = 0.44;
radialGauge.LabelInterval = 15;

In Visual Basic:

Dim radialGauge As UltraRadialGauge = New UltraRadialGauge
radialGauge.LabelExtent = 0.44
radialGauge.LabelInterval = 15
