Adding Labels to Pie Charts

To add multiple values to a Pie chart label you can create a label template like the following:

  <c1chart:C1Chart Name="c1Chart1" ChartType="Pie">

      <c1chart:C1Chart.Resources>

        <DataTemplate x:Key="lbl">

          <StackPanel>

            <StackPanel Orientation="Horizontal">

              <TextBlock Text="{Binding Path=Name}" />

              <TextBlock Text="=" />

              <TextBlock Text="{Binding Path=Value}" />

            </StackPanel>

            <TextBlock Text="{Binding Path=PercentageSeries,Converter={x:Static c1chart:Converters.Format}, ConverterParameter=#.#%}"/>

          </StackPanel>

        </DataTemplate>

      </c1chart:C1Chart.Resources>

      <c1chart:C1Chart.Data>

        <c1chart:ChartData>

          <c1chart:ChartData.ItemNames>P1 P2 P3 P4 P5</c1chart:ChartData.ItemNames>

          <c1chart:DataSeries Values="20 22 19 24 25" PointLabelTemplate="{StaticResource lbl}" />

        </c1chart:ChartData>

      </c1chart:C1Chart.Data>

      <c1chart:C1ChartLegend DockPanel.Dock="Right" />

    </c1chart:C1Chart>
