XAML

<xctk:Chart>
  <xctk:Chart.Areas>
    <xctk:Area x:Name="_area1" Title="Area #1">

      <xctk:Area.Series>
        <xctk:Series x:Name="_series"
                      DefaultInterior="BlueViolet"
                      Spacing="20"
                      Title="Average"
                      ShowPointsInLegend="false"
                      ShowHintLabels="false"
                      HintLineLength="20">
          <xctk:Series.Layout>
            <xctk:PieLayout />
          </xctk:Series.Layout>
          <xctk:Series.DataPoints>
            <xctk:DataPoint X="1" Y="1" Label="Oct" />
            <xctk:DataPoint X="2" Y="2" Label="Jan"/>
            <xctk:DataPoint X="2.5" Y="1.5" Label="Feb" />
            <xctk:DataPoint X="4" Y="1" Label="Jun"/>
            <xctk:DataPoint X="1.5" Y="3" Label="Dec"/>
            <xctk:DataPoint X="5" Y="5" Label="Apr"/>
            <xctk:DataPoint X="3" Y="1" Label="Nov"/>
            <xctk:DataPoint X="4.5" Y="7" Label="Jul"/>
            <xctk:DataPoint X="3.5" Y="4.5" Label="Aug"/>
          </xctk:Series.DataPoints>
        </xctk:Series>
      </xctk:Area.Series>
    </xctk:Area>
