RadialBarSeries<T, D> class

Renders the radial bar series.

The radial bar chart is used for showing the comparisons among the categories using the circular shapes. To render a radial bar chart, create an instance of RadialBarSeries, and add to the series collection property of SfCircularChart.

Provides options to customize the maximumValue, trackColor, trackBorderColor, trackBorderWidth, trackOpacity and useSeriesColor of the pie segments.
