Detailed Description

The QLineSeries class presents data in line charts.

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.

Destroys the object. Series added to QChartView or QChart instances are owned by the instances and deleted when the instances are destroyed.
