Charts API 構建於 Qt 圖形視圖框架之上。Charts 可以顯示為 QGraphicsWidget 使用 QChart 類。不管怎樣，還有方便類 QChartView ，其是 QWidget 基於。這些使我們能夠快速將 Qt Charts 用作正常 Qt 小部件。
若打算在應用程序中使用 Qt Charts C++ 類，使用以下 include 和 using 指令：
#include <QtCharts> using namespace QtCharts;
注意： 采用 Qt Creator 的 Qt Quick 應用程序嚮導創建的工程是基於 Qt Quick 2 的模闆使用 QGuiApplication 默認情況下。所有這種 QGuiApplication 實例在工程中均必須被替換采用 QApplication 因為模塊依賴於 Qt 的 圖形視圖框架 為渲染。
要鏈接到 Qt Charts 模塊，添加此行到
qmake
工程文件：
QT += charts
各圖錶類型的錶示通過 QAbstractSeries 派生類。要創建圖錶，用戶必須使用相關係列類的實例並將它添加到 QChart 實例。
QLineSeries* series = new QLineSeries(); series->append(0, 6); series->append(2, 4); ... chartView->chart()->addSeries(series); chartView->chart()->createDefaultAxes();
