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

[explicit] 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 noexcept] 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 an access function for property: QAbstractSeries::type.
