# C1RadialGauge Component C1RadialGauge provides many different properties to customize C1Radial Gauge control. See more demos, documentation, and samples here. ## Content [C1RadialGauge](/componentone/docs/win/online-gauges/) has the center point, radius, start and sweep angles. The [PointerOriginX](/componentone/docs/win/online-gauges/) and [PointerOriginY](/componentone/docs/win/online-gauges/) properties specify the center of the polar coordinate system associated with the gauge. The height or width of the working area (which is lesser) becomes the base dimension. The [Radius](/componentone/docs/win/online-gauges/) property specifies a portion of the base dimension whose length is 100 in logical coordinates. The [StartAngle](/componentone/docs/win/online-gauges/) and [SweepAngle](/componentone/docs/win/online-gauges/) properties provide the possible range of values for the angular coordinate. As opposed to the standard polar coordinates, the angle of 0° corresponds to the direction from center upwards.
![StartAngle and SweepAngle](https://cdn.mescius.io/document-site-files/images/2003d53a-81bd-40aa-82c0-56cd09293e5d/imagesext/image16_6.png) The **StartAngle** property defines an angle for the **C1GaugeBase.Minimum** value. The (**StartAngle** + **SweepAngle**) angle corresponds to the **C1GaugeBase.Maximum** value. You can reverse the direction of angular coordinate by setting the [IsReversed](/componentone/docs/win/online-gauges/) property to **True**. ## See Also [C1LinearGauge Component](/componentone/docs/win/online-gauges/gaugesforwinformscom/c1gaugeobjectsandusa/gaugecomponents/c1lineargaugecompone)
