详细说明

折线图用于将信息显示为一系列由直线连接的数据点。

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)

构造一个空的系列对象，它是parent 的子对象。当该系列对象被添加到QChartView 或QChart 实例时，其所有权将被转移。

`[virtual noexcept]` QLineSeries::~QLineSeries()

销毁对象。添加到QChartView 或QChart 实例的系列由实例拥有，并在销毁实例时被删除。

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

重构属性访问函数：QAbstractSeries::type 。
