    \class QLineSeries
    \brief The QLineSeries class is used for making line charts.

    \mainclass

	A line chart is used to show information as a series of data points
	connected by straight lines.

	\image linechart.png

	Creating basic line chart is simple:
	\code
	QLineSeries* series = new QLineSeries();
    series->append(0, 6);
    series->append(2, 4);
	...
	chartView->addSeries(series);
    \endcode
