Qt Graphs Widgets
The Qt Graphs module enables you to visualize data in 2D and 3D graphs.
In the 3D realm there is support for 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.
In the 2D realm, there is support for area, bar, donut, line, pie, scatter, and spline graphs, and they are easily combinable with any other QML content.
Qt Graphs is built on Qt 6 and the 3D graphs on Qt Quick 3D to take advantage of hardware acceleration and Qt Quick.
Using the Module
Using a Qt module's C++ API 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 GraphsWidgets)
target_link_libraries(mytarget PRIVATE Qt6::GraphsWidgets)
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 += graphswidgets
