Inherited Members
Namespace: Syncfusion.UI.Xaml.Charts
Assembly: Syncfusion.SfChart.WPF.dll
Syntax
public class BubbleSeries : XyDataSeries, ICloneable, ISupportAxes2D, ISupportAxes, ISegmentSelectable
Remarks

BubbleSeries requires an additional data binding parameter Size in addition to X,Y parameters. The size of each bubble depends on the size value given in the data point.MinimumRadius and MaximumRadius properties can be used to control the minimum and maximum radius of the symbols.

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