                         BarCategoriesAxis {

                         }
                     // Add a few series...

                 \mainclass
                 QAbstractBarSeries represents a series of data shown as bars. The purpose of this class is to draw bars to
                 the position defined by data. Single bar is defined by QPointF, where x value is the x-coordinate of the bar
                 and y-value is the height of the bar. The category names are ignored with this series and x-axis
                 shows the x-values.
                 See the \l {BarChart Example} {bar chart example} to learn how to create a simple bar chart.

                 Note that with QBarSeries this value means the width of one group of bars instead of just one bar.
