  I am trying to get the index of selected pie segment when the user clicks on the pie chart. I added the following to the on load function but the event isn’t firing when I click on the chart.

  var agingChart = new wijmo.chart.FlexPie(‘#agingChart’, {});
  
  …

  agingChart.selectionChanged.addHandler(function(e)
  
  {
  
  alert(e.selectedIndex);
  
  });

  Thanks, Ed

  Hi,

  For selecting a segment of pie chart, you need to change the selectionMode property of the chart to ‘Point’, as shown in the demo below:
