详细描述

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);

成员函数

QLineSeries::QLineSeries(QObject **parent* = Q_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.

QLineSeries::~QLineSeries()

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

`[virtual]` QAbstractSeries::SeriesType QLineSeries::type() const

Reimplemented from QAbstractSeries::type().
