Once the range has been defined, you can specify the angles that match the C1Gauge.Minimum and C1Gauge.Maximum values. The C1RadialGauge.StartAngle defines the position of the pointer when the C1Gauge.Value property is set to the C1Gauge.Minimum value in the range. The C1RadialGauge.SweepAngle specifies the rotation added to the C1RadialGauge.StartAngle when the C1Gauge.Value property is set to the C1Gauge.Maximum value in the range.

All angles are specified in degrees, measured clockwise from the top of the control. The angles may be negative, but the absolute value of the C1RadialGauge.SweepAngle may not exceed 360 degrees.
