Examples
      <syncfusion:PieSeries ItemsSource="{Binding Data}" XBindingPath="Year" YBindingPath="Value">
      </syncfusion:PieSeries>
      PieSeries series1 = new PieSeries();
      series1.ItemsSource = viewmodel.Data;
      series1.XBindingPath = "Year";
      series1.YBindingPath = "Value";
      chart.Series.Add(series1);
