                 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.

                 \class QPieSeries
                 \brief Pie series API for QtCommercial Charts
                 The pie series defines a pie chart which consists of pie slices which are defined as QPieSlice objects.
                 The slices can have any values as the QPieSeries will calculate its relative value to the sum of all slices.
                 The actual slice size is determined by that relative value.
                 Pie size and position on the chart is controlled by using relative values which range from 0.0 to 1.0
                 These relate to the actual chart rectangle.
                 By default the pie is defined as a full pie but it can also be a partial pie.
                 This can be done by setting a starting angle and angle span to the series.
                 Full pie is 360 degrees where 0 is at 12 a'clock.
                 See the \l {PieChart Example} {pie chart example} to learn how to create a simple pie chart.
