Hi Femil,
Thanks for using Syncfusion Products.
We can achieve your requirement by using ChartSelectionBehavior. The ChartSeries have a property called EnableDataPointSelection which enable ChartSelectionBehavior and it has two events SelectionChanged and SelectionChanging. The two events are used to view the details of selected datapoints. When the touch starts on datapoint location SelectionChanging event is called and SelectionChanged event is called at touches end. The following code example helps to explode the selected segment using SelectionChanged event.
Code Example:
DoughnutSeries doughnut = new DoughnutSeries ();
doughnut.EnableDataPointSelection = true;
doughnut.SelectedDataPointColor = Color.Green;
doughnut.ItemsSource = Data;
void Chart_SelectionChanged (object sender, ChartSelectionEventArgs e)
{
// below code set the selected segment index as explode index.
doughnut.ExplodeIndex = e.SelectedDataPointIndex;
}
We have prepared a sample based on the requirement. You can download the sample from the following location.
