39 \mainclass
40
41 QBoxPlotSeries represents a series of data shown as bars. The purpose of this class is to draw bars
42 as stacks, where bars in same category are stacked on top of each other.
43 QBoxPlotSeries groups the data from sets to categories, which are defined by QStringList.
44
45 See the \l {BoxPlotChart Example} {stacked bar chart example} to learn how to create a stacked bar chart.
