BubbleSeries2D.MinSize Property

Gets or sets the minimum size of the bubble marker.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v23.2.dll

NuGet Package: DevExpress.Wpf.Charts

Declaration

C#

public double MinSize { get; set; }

VB.NET

Public Property MinSize As Double

Property Value

Type	Description
Double	A Double value which specifies the marker’s minimum size (measured in X-axis units). The BubbleSeries2D.MaxSize and MinSize properties specify the marker’s size range on the X-axis. This value should be greater than 0.

Remarks

Bubble sizes are calculated automatically by default. Set the BubbleSeries2D.AutoSize property to false to manually specify maximum and minimum bubble sizes using the BubbleSeries2D.MaxSize and BubbleSeries2D.MinSize properties.

The BubbleSeries2D.MinSize property is intended to forcibly limit the minimum size of the marker when the weight of a series point is too high relative to the other series points, and this may affect the appearance of a chart.

When calculating a bubble’s size, the extreme values within a single series are taken into account. This means that the maximum value in a series determines the BubbleSeries2D.MaxSize of a bubble and the minimum value - its MinSize. These values are calculated in the measurement units of the X-axis.

Note that the BubbleSeries2D.MaxSize property’s value should be greater than the value of the MinSize property.

Example

The following example creates a 2D Bubble chart. Assign an XYDiagram2D object to the ChartControl.Diagram property and add a BubbleSeries2D object with points to the Diagram.Series collection.

This example also customizes the Y-axis’s whole range and a crosshair cursor.
