This topic explains, with code examples, how to configure ranges in the UltraLinearGauge™ control. This includes the number of ranges and their positions, lengths, widths, and formatting.

The UltraLinearGauge control supports multiple comparative ranges through populating its Ranges
collection.
Each range can be configured individually by specifying its starting and ending value (in the measures of the scale), fill color, and border thickness and color. The size of a comparative range in the across-the-scale is configurable by adjusting its inner and outer margins.
The following table explains briefly the configurable aspects of UltraLinearGauge control’s comparative ranges and maps them to properties that configure them.
The following table maps the desired behavior to its respective property settings.
The screenshot below demonstrates how a comparative range added to the UltraLinearGauge looks as a result of the following settings:
Following is the code that implements this example.
In C#:
var range1 = new LinearGraphRange();
range1.Brush = new SolidColorBrush(Color.FromArgb(0, 255, 0));
range1.Caption = "range1";
range1.StartValue = 6;
range1.EndValue = 89;
range1.InnerEndExtent = .5;
range1.InnerStartExtent = .5;
range1.OuterEndExtent = .8;
range1.OuterStartExtent = .8;
range1.Outline = new SolidColorBrush(Color.FromArgb(0, 0, 0));
In Visual Basic:
Dim range1 As New LinearGraphRange
With range1
.Brush = New SolidColorBrush(Color.FromArgb(0, 255, 0))
.Caption = "range1"
.StartValue = "6"
.EndValue = "89"
.InnerEndExtent = ".5"
.InnerStartExtent = ".5"
.OuterEndExtent = ".8"
.OuterStartExtent = ".8"
.Outline = New SolidColorBrush(Color.FromArgb(0, 0, 0))
End With
