Imports Infragistics.UltraGauge.Resources
If you want more than two colors on a property of your gauge to blend into each other in a circular way, apply the Multi-Stop Radial Gradient brush element to the property.
To apply the Multi-Stop Radial Gradient brush element to a property of your gauge using code:
Before you start writing any code, you should place using/Imports directives in your code-behind so you don’t need to always type out a member’s fully qualified name.
In Visual Basic:
Imports Infragistics.UltraGauge.Resources
In C#:
using Infragistics.UltraGauge.Resources;
Create the load event.
Create instances of the classes.
In Visual Basic:
Dim multiStopRadialGradientBrushElement1 As _ New MultiStopRadialGradientBrushElement() Dim colorStop1 As NewColorStop() Dim colorStop2 As New ColorStop() Dim colorStop3 As New ColorStop() Dim myRadialGauge As RadialGauge = Me.UltraGauge1.Gauges(0) Dim centerPoint As New System.Drawing.PointF() Dim focusScales As New System.Drawing.PointF()
In C#:
MultiStopRadialGradientBrushElement multiStopRadialGradientBrushElement1 = new MultiStopRadialGradientBrushElement(); ColorStop colorStop1 = new ColorStop(); ColorStop colorStop2 = new ColorStop(); ColorStop colorStop3 = new ColorStop(); RadialGauge myRadialGauge = this.ultraGauge1.Gauges[0] as RadialGauge; System.Drawing.PointF centerPoint = new System.Drawing.PointF(); System.Drawing.PointF focusScales = new System.Drawing.PointF();
Set the following properties:
start color — Black
end color — 254, 127, 0
one color stop (stop: 0.264; color: 186, 0 ,0)
focus scale — 0, 0
center point — 75, 25
