DxRangeSelectorChart.MinBubbleSize Property

Specifies the diameter of the smallest bubble in a bubble series.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(12)]
[Parameter]
public double MinBubbleSize { get; set; }

Property Value

Type	Default	Description
Double	12	The bubble diameter in pixels.

Remarks

The bubble diameter in DxChartBubbleSeries<T, TArgument, TValue, TSize> is specified by the SizeField property. To define the diameter of the smallest bubble, specify the MinBubbleSize property.

The following code snippet calculates the biggest bubble’s diameter based on the height of the Range Selector’s background area and changes the diameter of the smallest bubble:

    <DxRangeSelectorChart MaxBubbleSize="0.25"
