    \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
*/
/*!
    \qmlclass LineSeries QLineSeries
    \inherits XYSeries

    The following QML shows how to create a simple line chart:
