\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.

Creating basic line chart is simple:

|
|
\code
|
|
|
QLineSeries* series = new QLineSeries();
|
|
|
series->add(0, 6);
|
|
|
series->add(2, 4);
|
|
|
...
|
|
|
chartView->addSeries(series);
|

\endcode
