    \class QGroupedBarSeries
    \brief Series for creating grouped bar chart
    \mainclass

    QGroupedBarSeries represents a series of data shown as bars. The purpose of this class is to draw bars
    as groups, where bars in same category are grouped next to each other. QGroupedBarSeries groups the data
    from sets to categories, which are defined by a QStringList.

    See the \l {GroupedbarChart Example} {grouped bar chart example} to learn how to create a grouped bar chart.
