  Is there a way to show or hide the chart legend from the code behind? I have a small pie chart on the screen and user can click on it to zoom in. I would like to show the legend only when the chart is zoomed in. However, I am not able to find a reference to the legend object from the c1chart object.

  Thank you

  Hello,

  Add name to the legend in xaml and then you can change its visibility in code: legend.Visibility = ...

  Hi,

  You can show or hide FlexPie/FlexChart legend by setting LegendPosition property as:

          private void LegendChecked_Changed(object sender, RoutedEventArgs e)
          {
              if((sender as CheckBox).IsChecked.Value)
                  flexPie.LegendPosition = C1.Chart.Position.Auto;
              else
                  flexPie.LegendPosition = C1.Chart.Position.None;
          }

  Please refer the attached sample for the same: FlexPieDemo.zip

  Best Regards,
