    Syntax
    public class BubbleSeries : XyDataSeries, ISupportAxes, ISegmentSelectable
    Remarks

    BubbleSeries requires an additional data binding parameter Size in addition to the X,Y parameters.

    To render a series, create an instance of BubbleSeries class, and add it to the Series collection.

    It provides options for Fill, PaletteBrushes, StrokeThickness, and opacity to customize the appearance.

    Size - Specify the bubble size using the Size property.

    LegendIcon - To customize the legend icon using the LegendIcon property.

    EnableTooltip - A tooltip displays information while tapping or mouse hovering over a segment. To display the tooltip on a chart, you need to set the EnableTooltip property as true in BubbleSeries class, and also refer TooltipBehavior property.

    Data Label - Data labels are used to display values related to a chart segment. To render the data labels, you need to set the ShowDataLabels property as true in BubbleSeries class. To customize the chart data labels alignment, placement, and label styles, you need to create an instance of CartesianDataLabelSettings and set to the DataLabelSettings property.

    Animation - To animate the series, set True to the EnableAnimation property.
