BubbleSeries2D.MaxSize Property

Gets or sets the maximum size of the bubble marker.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v21.2.dll


public double MaxSize { get; set; }

Property Value

Type Description

A Double value which specifies the marker’s maximum size (measured in X-axis units). The BubbleSeries2D.MinSize and MaxSize properties specify the marker’s size range on the X-axis.

This value should be greater than 0.


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.MaxSize property is intended to forcibly limit the maximum 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 MaxSize of a bubble and the minimum value - its BubbleSeries2D.MinSize. These values are calculated in the measurement units of the X-axis.

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


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.
