Remarks

Each point in a bubble series has an argument, a regular value and a size value. Arguments are provided by the BootstrapChartCommonSeriesBase.ArgumentField; regular values are provided by the BootstrapChartSeries.ValueField; size values are provided by the SizeField.

Size values do not specify the real sizes of bubbles directly, they only define the sizes of bubbles in relation to each other. Apart from a size value, the real, pixel-measured size of a bubble depends on the BootstrapChart.MinBubbleSize and BootstrapChart.MaxBubbleSize values and the size of the BootstrapChartSeriesBase.Pane.

Commonly, a chart contains several series, and many of them have the same size field. In this case, assign the name of this field to the SizeField property of the BootstrapChartSeries object. If a series must have a unique size field, specify the same property, but do so in the series object within the BootstrapChartSeriesCollection array.
