\class QAreaSeries
\brief The QAreaSeries class is used for making area charts.
\mainclass
Jani Honkonen
astyle and manual coding style fixes for src-folder
r2097 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.
Marek Rosa
Few docs fixes to area series
r1515 In that case QAreaSeries should be initiated with two QLineSeries instances. Please note terms "upper" and "lower" boundary can be misleading in cases
Jani Honkonen
astyle and manual coding style fixes for src-folder
r2097 where "lower" boundary had bigger values than the "upper" one, however the main point that area between these two boundary lines will be filled.
