    \class QPercentBarSeries
    \brief part of QtCommercial chart API.
    \mainclass

    QPercentBarSeries represents a series of data shown as bars. The purpose of this class is to draw bars
    as stacks, where each bar is shown as percentage of all bars in that category.
    QPercentBarSeries groups the data from sets to categories, which are defined by a QStringList.

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