This sample shows GDP growth of various countries for a few years in the polar and radar charts using the stacked area series.
In this example, you can see how to render and configure polar and radar charts with stacking area series. Switching between polar and radar series can be done using Series Type in the property panel.
Injecting Module
Chart component features are segregated into individual feature-wise modules. To use stacking area series, we need to inject StackingAreaSeries, PolarSeries and SRadarSeries module into services.
More information on the polar-radar series can be found in this documentation section.
