Radial Gauges (Vue)

Radial gauges display a metric as a percentage of the length of a circular scale, like a pie or donut chart with a single slice.

By default, the radial scale displays a 180-degree arc. You can change that by adjusting its start and sweep angles. If the autoScale property is set to true, the control will automatically scale the gauge to fill the host element taking onto account the startAngle and sweepAngle properties.

Use the controls below to see the effect of the main RadialGauge properties:

This example uses Vue.
