Qt Charts

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.

Using the Module

QML API

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:

import QtCharts

C++ API

Using a Qt module requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake.

Building with CMake

Use the find_package() command to locate the needed module component in the Qt6 package:

find_package(Qt6 REQUIRED COMPONENTS Charts)
target_link_libraries(mytarget PRIVATE Qt6::Charts)

For more details, see the Build with CMake overview.

Building with qmake

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

Note: Projects created with Qt Creator's Qt Quick Application wizard are based on the Qt Quick 2 template that 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.
