Detailed Description
A line chart is used to show information as a series of data points connected by straight lines.

Creating a basic line chart is simple:
QLineSeries* series = new QLineSeries(); series->append(0, 6); series->append(2, 4); ... chart->addSeries(series);
Member Function Documentation
QLineSeries::QLineSeries(QObject *parent = nullptr)
Constructs an empty series object that is a child of parent. When the series object is added to a QChartView or QChart instance, the ownership is transferred.
[virtual] QLineSeries::~QLineSeries()
Destroys the object. Series added to QChartView or QChart instances are owned by the instances and deleted when the instances are destroyed.
[override virtual] QAbstractSeries::SeriesType QLineSeries::type() const
Reimplements: QAbstractSeries::type() const.
