    \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 QLineSerie 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.

	Creating basic area chart is simple:
	\code
	QLineSeries* lineSeries = new QLineSeries();
	series->add(0, 6);
	series->add(2, 4);
	QAreaSeries* areaSeries = new QAreaSeries(lineSeries);
	...
	chartView->addSeries(areaSeries);
    \endcode
