C1RadialGauge uses a rotating pointer to show a value along a curved scale. The value is represented by a Value property and the range is defined by the Min and Max properties. The C1RadialGauge control appears similar to a typical speedometer:

Creating and using a C1RadialGauge control typically involves the following steps:

1. Creating the C1RadialGauge control and setting its main properties: C1Gauge.Min, C1Gauge.Max, C1RadialGauge.StartAngle, and C1RadialGauge.SweepAngle.
2. Adding C1Gauge.TickMajor and C1Gauge.TickMinor decorators to show the scale and GaugeLabel to customize the label.
3. Optionally adding GaugelRange decorators to highlight parts of the scale. Ranges are typically used to indicate ranges that are too low, acceptable, or too high. Ranges can also be dynamic, moving automatically when the C1Gauge.Value property changes.
4. Optionally customizing gauge elements with templates.
5. Setting the C1Gauge.Value property to display the value you want to show.
