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。
若打算在应用程序中使用 Qt Charts C++ 类，使用以下 include 和 using 指令：
#include <QtCharts> using namespace QtCharts;
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。
要链接到 Qt Charts 模块，添加此行到
qmake
工程文件：
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();
