    \brief Series for creating bar chart.

    QBarSeries 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. QBarSeries groups the data
    from sets to categories, which are defined by a QStringList.

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