Configuring Ranges (UltraRadialGauge)

Purpose

This topic provides a conceptual overview of the UltraRadialGauge™ control’s ranges. It describes the properties of the ranges and provides an example of how to add ranges to the radial gauge.

Required background

The following topics are prerequisites to understanding this topic:

Topic Purpose

This section gives you an overview of the UltraRadialGauge™ control and its main features.

This topic explains using a code example how to add the UltraRadialGauge™ control to a Windows Forms application.

This topic contains the following sections:

Ranges Overview

Ranges overview

A range highlights a set of continuous values bound by a specified minimum and maximum value on a gauge scale. You can add multiple ranges to a scale, specifying different brushes, along with starting and ending values. To add a range to the UltraRadialGauge control, create a RadialGaugeRange object and add it to the Ranges collection.

Preview

The following image is a preview of the UltraRadialGauge control with the three ranges added to it (0-3; 3-7 and 7-10).

Range Properties

Range properties summary

The following table summarizes the properties of the RadialGaugeRange.

Property Name Property Type Description

Brush

The color assigned to the range

Double

The starting value at which to begin the range

Double

The ending value at which to end the range

Double

The distance from the center of the gauge (typically from 0 to 1) at which to start rendering the inner sweep of the range. Use values further from 0 than 1 to make the range extend beyond the normal radius of the gauge.

Double

The distance from the center of the gauge (typically from 0 to 1) at which to end rendering the inner sweep of the range. Use values further from 0 than 1 to make the range extend further than the normal radius of the gauge.

Double

The distance from the center of the gauge (from 0 to 1) at which to start rendering the outer sweep of the range. Use values further from 0 than 1 to make this extend further than the normal radius of the gauge.

Double

The distance from the center of the gauge (from 0 to 1) at which to end rendering the outer sweep of the range. Use values further from 0 than 1 to make this extend further than the normal radius of the gauge.

Configuring the Range

Example

The following screenshot demonstrates how the UltraRadialGauge control renders using this RadialGaugeRange configuration:

Following is the code that implements this example

In C#:

var range1 = new RadialGaugeRange();
range1.Brush = new SolidColorBrush(Color.Blue);
range1.StartValue = 0;
range1.EndValue = 20;
range1.OuterStartExtent = 0.5;
range1.OuterEndExtent = 0.4;
radialGauge.Ranges.Add(range1);

In Visual Basic:

Dim range1 As RadialGaugeRange = New RadialGaugeRange()
range1.Brush = New SolidColorBrush(Color.Blue)
range1.StartValue = 0
range1.EndValue = 20
range1.OuterStartExtent = 0.5
range1.OuterEndExtent = 0.4
radialGauge.Ranges.Add(range1)
