\brief The QHorizontalStackedBarSeries class presents a series of data as horizontally
stacked bars, with one bar per category.
Each bar set added to the series contributes a single segment to each stacked bar.
See the \l {Charts with Widgets Gallery} to learn how to create a horizontal stacked bar chart.

\brief Presents a series of data as stacked horizontal bars, with one bar per category.
Each bar set added to the series contributes a single segment to each stacked bar.
