Qt Data Visualization module provides a way to visualize data in 3D as bar, scatter, and surface graphs. It is 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 to them.

Qt Data Visualization is built on Qt 5 and OpenGL to take advantage of hardware acceleration and Qt Quick 2.

Getting Started

To import Qt Data Visualization QML types, add the following import statement to your .qml file:

import QtDataVisualization 1.14

If you intend to use Qt Data Visualization C++ classes in your application, use the following include and using directives:

#include <QtDataVisualization>

using namespace QtDataVisualization;

Note: If you are only using a few classes from this module, we recommend including only those specific classes instead of the whole module.

To link against the Qt Data Visualization module, add this line to your qmake project file:

QT += datavisualization
