DxChartBubbleSeries<T, TArgument, TValue, TSize> Class

Defines a bubble series.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.1.dll

Declaration

public class DxChartBubbleSeries<T, TArgument, TValue, TSize> :
    DxChartXYSeries<T, TArgument, TValue, TSize>

Type Parameters

Name	Description
T	The type of data.
TArgument	The type of series arguments.
TValue	The type of series values.
TSize	The type of series size values.

Remarks

The bubble series displays data as individual bubbles of different sizes.

Use the chart’s Data property to specify an IEnumerable<T> data source, and the ArgumentField and ValueField properties to specify data source fields that contain arguments and values. To specify a data source field that supplies bubble sizes, use the DxChartBubbleSeries.SizeField property. For a sample data source, refer to our GitHub repository.
