  3. Assign data source fields that contain arguments and values for data points to ArgumentField and ValueField properties.
  4. Optional. Configure the series: customize appearance, add labels, choose selection and hover modes, etc.
<DxPolarChart Data=@DataSource>
    <DxPolarChartLineSeries ArgumentField="@((DiscretePoint i) => i.Arg)"
                            ValueField="@((DiscretePoint i) => i.Day)">
    </DxPolarChartLineSeries>
    <DxChartLegend Visible="false" />
</DxPolarChart>

DxChartSeriesLabel
Defines a series label.
DxChartSeriesLegendItem

                            ValueField="@((DiscretePoint i) => i.Day)">
        <DxChartSeriesLabel Visible="true" FormatPattern="{value:##.#}" />
        <DxChartSeriesPoint Color="Color.SlateBlue" />
        <DxChartSeriesLegendItem Text="Daily Temperature" />
