\class QAreaSeries
\inmodule QtCharts
\brief The QAreaSeries class presents data in area charts.
An area series is used to show quantitative data. It is based on a line series, in the way that
the area between the boundary lines is emphasized with color. Since the area series is based on
the line series, the QAreaSeries constructor needs a QLineSeries instance, which defines the
\e upper boundary of the area. The area chart is drawn using the bottom of the plot area as the
\e lower boundary by default. Instead of the bottom of the plot area, the lower boundary can be
specified by another line. In that case, QAreaSeries should be initialized with two QLineSeries
instances.
\note The terms \e upper and \e lower boundary can be misleading in cases where the value of the
lower boundary is greater than that of the upper boundary. The main point is that the
area between these two boundary lines will be filled.
See the \l {Charts with Widgets Gallery} to learn how to create a simple area chart.
