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

Creating and using a C1RadialGauge typically involves the following steps:

1. Creating the C1RadialGauge control and setting its main properties: Minimum, Maximum, StartAngle, and SweepAngle.
2. Adding C1GaugeMark and C1GaugeLabel decorators to show the scale. Each element may show a set of labels, tick marks, or both.
3. Optionally adding C1GaugeRange 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 Value property changes.
4. Optionally customizing gauge elements with XAML templates.
5. Setting the Value property to display the value you want to show.
