    \class QAbstractBarSeries
    \brief Series for creating a bar chart
    \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.

    The width of the bars of the series. The unit of \a width is the unit of x-axis. The minimum width for bars
    is zero and negative values are treated as zero. Setting the width to zero means that width of the bar on screen
    is one pixel no matter what the scale of x-axis is. Bars wider than zero are scaled with x-axis.
    Note that with QBarSeries this value means the width of one group of bars instead of just one bar.
