    \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 examples_linechart.png

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

    When series object is added to QChartView or QChart instance ownerships is transferred.
