Inherits from IGSeriesDataSourceHelper : NSObject
Declared in IGSeriesDataSourceHelper.h

Overview

This data source helper is used to create a data source usable by bubble series. The data points of this data source are numeric value pairs to be used in a cartesian coordinate system and a radius value for the size of the bubble marker. This data source accepts an array of values and creates a sequence of IGBubblePoint objects for the series.
