Qt Data Visualization

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.

使用模块

QML API

The QML types of the module are available through the QtDataVisualization 导入。要使用类型,添加以下 import 语句到 .qml 文件:

import QtDataVisualization
					

C++ API

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 .

构建采用 CMake

使用 find_package() command to locate the needed module component in the Qt6 包:

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

更多细节,见 构建采用 CMake 概述。

采用 qmake 构建

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
