\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->add(0, 6);
series->add(2, 4);
...
chartView->addSeries(series);
\endcode
