\brief Shows how to create a simple area chart.
\include gallery.qdocinc

To create area charts, we need two QLineSeries instances. They are going to define the upper and lower boundary of the area.
\snippet chartsgallery/areawidget.cpp 1
We add data to both series and use the stream operator.
\snippet chartsgallery/areawidget.cpp 2
Now we create a QAreaSeries instance using two line series objects. We set the custom gradient fill and width of the outline.
\snippet chartsgallery/areawidget.cpp 3
Last we create the QChartView instance, set the title, set anti-aliasing, and add the area series. We also create the default axes and specify the ranges on them.
\snippet chartsgallery/areawidget.cpp 4
The chart is ready to be shown.
