Qt Charts

Qt Charts module provides a set of easy to use chart components. It uses the Qt Graphics View Framework, therefore charts can be easily integrated to modern user interfaces. Qt Charts can be used as QWidgets, QGraphicsWidget, or QML types. Users can easily create impressive graphs by selecting one of the charts themes.

Getting Started

To import Qt Charts QML types, add the following import statement to your .qml file:


  import QtCharts 2.0

If you intend to use Qt Charts C++ classes in your application, use the following include and using directives:


  #include <QtCharts>

  using namespace QtCharts;

Note: Since Qt Creator 3.0, projects created with Qt Quick Application wizard based on the Qt Quick 2 template uses QGuiApplication by default. All such QGuiApplication instances in the project must be replaced with QApplication as the module depends on Qt's Graphics View Framework for rendering.

To link against the Qt Charts module, add this line to your qmake project file:


  QT += charts
