                 \class QAreaSeries
                 \brief The QAreaSeries class is used for making area charts.
                 \mainclass
                 An area chart is used to show quantitative data. It is based on line chart, in the way that area between axis and the line
                 is emphasized with color. Since the area chart is based on line chart, QAreaSeries constructor needs QLineSeries instance,
                 which defines "upper" boundary of the area. "Lower" boundary is defined by default by axis X. Instead of axis X "lower" boundary can be specified by other line.
                 In that case QAreaSeries should be initiated with two QLineSeries instances. Please note terms "upper" and "lower" boundary can be misleading in cases
                 where "lower" boundary had bigger values than the "upper" one, however the main point that area between these two boundary lines will be filled.
                 See the \l {AreaChart Example} {area chart example} to learn how to create a simple area chart.
