The Qt Charts module provides a set of easy-to-use chart components. It uses the Qt Graphics View Framework to integrate charts with modern user interfaces. Qt Charts can be used as QWidgets, QGraphicsWidget, or QML types. Users can easily create impressive charts by selecting one of the themes.
The Qt Charts QML API is an intuitive and simple way to show charts in your QML applications.
This example shows how to create a simple line chart:
The QML types of the module are available through the
QtCharts import. To use the types, add the following import statement to your .qml file:
Note: An instance of QApplication is required for the QML types as the module depends on Qt's Graphics View Framework for rendering. QGuiApplication is not sufficient. However, projects created with Qt Creator's Qt Quick Application wizard are based on the Qt Quick template that uses QGuiApplication by default. All the QGuiApplication instances in such projects must be replaced with QApplication.
find_package() command to locate the needed module component in the
find_package(Qt6 REQUIRED COMPONENTS Charts)
target_link_libraries(mytarget PRIVATE Qt6::Charts)
For more details, see the Build with CMake overview.
To configure the module for building with qmake, add the module as a value of the
QT variable in the project's .pro file:
QT += charts
