DxRangeSelectorChart.MaxBubbleSize Property

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

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(0.2)]
[Parameter]
public double MaxBubbleSize { get; set; }

Property Value

Type	Default	Description
Double	0.2	The ratio between the biggest bubble’s diameter and the smaller chart side.

Remarks

The bubble diameter (size) in DxChartBubbleSeries<T, TArgument, TValue, TSize> is specified by the SizeField property. To calculate the diameter of the biggest bubble, the DxRangeSelectorChart component uses the following formula:

d = MaxBubbleSize * min(height, width), where height and width are the sizes of the Range Selector’s background area.

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:

<DxRangeSelector Data="@chartsData"
                 Width="100%"
                 Height="300px">
    <DxTitleSettings Text="Correlation between Total Population and Population with Age over 60" />
    <DxRangeSelectorChart MaxBubbleSize="0.25"
