The Qt Data Visualization module enables you to visualize data in 3D as bar, scatter, and surface graphs. It's especially useful for visualizing depth maps and large quantities of rapidly changing data, such as data received from multiple sensors. The look and feel of graphs can be customized by using themes or by adding custom items and labels.
Qt Data Visualization is built on Qt 6 and OpenGL to take advantage of hardware acceleration and Qt Quick 2.
The QML types of the module are available through the QtDataVisualization import. To use the types, add the following import statement to your .qml file:
import QtDataVisualization
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.
Use the find_package() command to locate the needed module component in the Qt6 package:
find_package(Qt6 REQUIRED COMPONENTS DataVisualization)
target_link_libraries(mytarget PRIVATE Qt6::DataVisualization)
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 += datavisualization
Qt Data Visualization is available under commercial licenses from The Qt Company. In addition, it is available under the GNU General Public License, version 3. See Qt Licensing for further details.
