42 \brief The QStackedBarSeries class presents a series of data as vertically stacked bars,
43 with one bar per category.
44
45 Each bar set added to the series contributes a single segment to each stacked bar.
46
47 See the \l {StackedbarChart Example} {stacked bar chart example} to learn how to create a stacked bar chart.
