BubbleSeries2D.AutoSize Property

Gets or sets the value indicating whether bubble sizes are calculated automatically.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v19.1.dll

Declaration

C#

public bool AutoSize { get; set; }

VB.NET

Public Property AutoSize As Boolean

Property Value

Type	Description
Boolean	true, if bubble sizes should be calculated automatically; otherwise, false.

Remarks

The AutoSize property is set to true by default. In this case, the BubbleSeries2D.MinSize and BubbleSeries2D.MaxSize properties have no affect on bubble sizes. Set the AutoSize property to false to manually specify maximum and minimum bubble sizes using the BubbleSeries2D.MaxSize and BubbleSeries2D.MinSize properties.

Example

The following example demonstrates how to create a 2D Bubble chart. To do this, it is necessary to assign the ChartControl.Diagram property to XYDiagram2D, and then add a BubbleSeries2D object with points to the diagram’s Diagram.Series collection.

Also, this example shows how to customize the Y-axis whole range and a crosshair cursor.
