使用 QtGraphs 代替。
Charts API 构建于 Qt 图形视图框架之上。Charts 可以显示为 QGraphicsWidget 使用 QChart 类。不管怎样，还有方便类 QChartView ，其是 QWidget 基于。这些使我们能够快速将 Qt Charts 用作正常 Qt 小部件。
注意： The Qt Charts module has been deprecated since Qt 6.10. For new projects, use the Qt Graphs module instead. Qt Graphs uses each platform's native rendering backend (Metal on macOS, DirectX on Windows, OpenGL or Vulkan on Linux) to achieve hardware-accelerated rendering for both 2D and 3D graphs. Qt Graphs uses Qt Quick 形状 for 2D graph rendering, instead of the outdated Qt Graphics View Framework used by the Qt Charts module. To migrate from Qt Charts to Qt Graphs module, refer to Qt Graphs Migration from Qt Charts .
Using a Qt module's C++ API requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake.
注意： 采用 Qt Creator 的 Qt Quick 应用程序向导创建的工程是基于 Qt Quick 2 的模板使用 QGuiApplication 默认情况下。所有这种 QGuiApplication 实例在工程中均必须被替换采用 QApplication 因为模块依赖于 Qt 的 图形视图框架 为渲染。
要将模块用于 CMake，使用
find_package()
命令定位所需模块组件在
Qt6
包：
find_package(Qt6 COMPONENTS Charts REQUIRED)
target_link_libraries(mytarget PRIVATE Qt6::Charts)
要采用 qmake 构建模块，将模块添加作为值对于
QT
变量在工程的 .pro 文件：
QT += charts
各图表类型的表示通过 QAbstractSeries 派生类。要创建图表，用户必须使用相关系列类的实例并将它添加到 QChart 实例。
QLineSeries* series = new QLineSeries(); series->append(0, 6); series->append(2, 4); ... chartView->chart()->addSeries(series); chartView->chart()->createDefaultAxes();
