详细说明
折线图用于将信息以一系列由直线连接的数据点的形式呈现。
创建一个基本的折线图非常简单：
QLineSeries* series = new QLineSeries();
series->append(0, 6);
series->append(2, 4);
...
chart->addSeries(series);成员函数文档
[explicit] QLineSeries::QLineSeries(QObject *parent = nullptr)
创建一个空的系列对象，该对象是parent 的子对象。当该系列对象被添加到 QChartView 或 QChart 实例中时，所有权将随之转移。
[virtual noexcept] QLineSeries::~QLineSeries()
销毁该对象。添加到 QChartView 或 QChart 实例中的系列由这些实例拥有，并在实例被销毁时被删除。
[override virtual] QAbstractSeries::SeriesType QLineSeries::type() const
重新实现了属性QAbstractSeries::type 的访问函数。
