\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->append(0, 6);
|
|
|
series->append(2, 4);
|
|
|
...
|
|
|
chart->addSeries(series);
|

\endcode
