A ChartItem represents a single item in a ChartSeries. In most standard series, there is one ChartItem created for each item in the series' dataProvider collection. ChartItems are passed to the instances of a series' itemRenderer for rendering. Most Series types extend ChartItem to contain additional information specific to the chart type.
