QSplineSeries Class
QSplineSeries 类将数据以样条图的形式呈现。更多内容...
| Header: | #include <QSplineSeries> |
| In QML: | SplineSeries |
| Inherits: | QLineSeries |
| Status: | Deprecated |
该类已弃用。我们强烈建议不要在新代码中使用它。
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
样条系列用于存储数据点以及QPainterPath 绘制样条曲线所需的线段控制点。当数据发生变化时，系统会自动计算控制点。该算法通过计算这些点，确保能够绘制出标准样条曲线。
以下代码片段演示了如何创建一个基本的样条图：
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)
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 QChart 实例中时，所有权将被转移。
[virtual noexcept] QSplineSeries::~QSplineSeries()
删除样条曲线系列。
[override virtual] QAbstractSeries::SeriesType QSplineSeries::type() const
重新实现了：QLineSeries::type() const。
