Charts - Pie series

Use the Pie Chart’s Data property to specify an IEnumerable<T> data source. The chart should contain at least one series to display data. Use the following series properties to bind the data source fields to the series:

  • ArgumentField: specifies the data source field that contains arguments for chart points.
  • ValueField: specifies the data source field that contain values for chart points.
