    \brief The QAreaSeries class presents data in area graphs.

    An area graph is used to draw an area composed by points.
    The points are defined by two series: upperSeries and lowerSeries.
    The area between the series is drawn as a graph. If only the upperSeries
    is defined, the area is then between the bottom of the graph and the upper series.
