QSplineSeries Class

QSplineSeries 类以样条曲线图的形式显示数据。更多

公共函数

	QSplineSeries(QObject *parent = nullptr)
virtual	~QSplineSeries()

重新实现的公共函数

virtual QAbstractSeries::SeriesType type() const override

详细说明

样条曲线系列存储QPainterPath 绘制样条曲线所需的数据点和线段控制点。当数据发生变化时，控制点会自动计算。算法会计算这些点，以便绘制法线样条曲线。

以下代码片段说明了如何创建基本的样条线图：

QSplineSeries* series = new QSplineSeries();
series->append(0, 6);
series->append(2, 4);
...
chart->addSeries(series);

成员函数文档

`[explicit]` QSplineSeries::QSplineSeries(QObject **parent* = nullptr)

构造一个空的系列对象，它是parent 的子对象。当系列对象被添加到QChart 实例时，所有权将发生转移。

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

删除样条曲线系列。

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

重实现：QLineSeries::type() const.
