Remarks

Use the Data property to bind the Polar Chart to a data source. Assign data source fields that contain arguments and values for data points to ArgumentField and ValueField properties.

The following example specifies the Arg field as the argument source and the Day field as the value source:

<DxPolarChart Data=@DataSource>
    <DxPolarChartAreaSeries ArgumentField="@((DiscretePoint i) => i.Arg)"
                            ValueField="@((DiscretePoint i) => i.Day)">
    </DxPolarChartAreaSeries>
    <DxChartLegend Visible="false" />
</DxPolarChart>
