Series.BubbleSize Property

Gets or sets data used to specify the size of bubbles in a bubble chart.

Namespace: DevExpress.Spreadsheet.Charts

Assembly: DevExpress.Spreadsheet.v23.2.Core.dll

NuGet Package: DevExpress.Spreadsheet.Core

Declaration

C#

ChartData BubbleSize { get; set; }

VB.NET

Property BubbleSize As ChartData

Property Value

Type	Description
ChartData	A ChartData object specifying data to plot.

Remarks

This example creates a bubble chart by adding series to an empty chart of the ChartType.Bubble type. The Series.BubbleSize property specifies data visualized as the diameter of the bubble associated with a data point. To display the value of the bubble size in the data label, the DataLabelBase.ShowBubbleSize property is set to true.
