    \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 {HorizontalStackedBarChart Example} {horizontal stacked bar chart example} 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.
