40 \brief The QHorizontalStackedBarSeries class presents a series of data as horizontally
41 stacked bars, with one bar per category.
42
43 Each bar set added to the series contributes a single segment to each stacked bar.
44
45 See the \l {HorizontalStackedBarChart Example} {horizontal stacked bar chart example} to learn how to create a horizontal stacked bar chart.
