In C#:
SolidFillBrushElement mySolidFillBrushElement1 = new SolidFillBrushElement();
Set the following color properties:
Type — Solid
Color — White
In Visual Basic:
mySolidFillBrushElement1.Color = System.Drawing.Color.White myScale.Labels.BrushElement = mySolidFillBrushElement1
In C#:
mySolidFillBrushElement1.Color = System.Drawing.Color.White; myScale.Labels.BrushElement = mySolidFillBrushElement1;
Set the following properties:

System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Pixel)
myScale.Labels.Frequency = 20
myScale.Labels.Orientation = _
Infragistics.UltraGauge.Resources.RadialLabelOrientation.Horizontal
myScale.Labels.SpanMaximum = 18
In C#:
myScale.Labels.Extent = 65;
myScale.Labels.Font =
new System.Drawing.Font("Arial", 14F,
System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Pixel);
myScale.Labels.Frequency = 20;
myScale.Labels.Orientation =
