\brief The QLineSeries class presents data in line charts.
A line chart is used to show information as a series of data points
connected by straight lines.
\image examples_linechart.png
Creating a basic line chart is simple:
\code
QLineSeries* series = new QLineSeries();
series->append(0, 6);
series->append(2, 4);
...
chart->addSeries(series);
\endcode
