                 QBarSeries represents a series of data shown as bars. One QBarSeries can contain multiple
                 QBarSet data sets. QBarSeries groups the data from sets to categories, which are defined
                 by QStringList.
                 See the \l {BarChart Example} {bar chart example} to learn how to create a simple bar chart.
