# Adjusting the Starting and Sweep Angles

Learn how to adjust starting and sweep angles in C1Gauge. See more demos, documentation, and samples here.

## Content



[C1RadialGauge](/componentone/docs/win/online-gauges/) supports various radial shapes including helical, clamshell, and half-circular. We will create these shapes in the next section, but first we can modify the start and sweep angles of the gauge scale to match any of these face shapes.

The StartAngle property defines an angle for the [Minimum](/componentone/docs/win/online-gauges/) value. The [StartAngle](/componentone/docs/win/online-gauges/) **+** [SweepAngle](/componentone/docs/win/online-gauges/) properties correspond to the [Maximum](/componentone/docs/win/online-gauges/) value.

Let’s reduce the arc of our scale by setting the **StartAngle** to **-130** and the **SweepAngle** to **260**.

1.  Click the **ellipsis** button next to the [Gauges](/componentone/docs/win/online-gauges/) property in the Properties window. The **C1Gauge.Gauges Collection Editor** dialog box opens.
2.  Set the StartAngle property to **-130**.
3.  Set the SweepAngle property to **260**.
