Qt Data Visualization

Qt Data Visualization module provides a way to visualize data in 3D.

Features

Multiple data visualization options: 3D Bars, 3D Scatter, and 3D Surface
2D slice views of the 3D data
Interactive data: rotate, zoom, and highlight data using mouse or touch
Uses OpenGL for rendering the data
QML2 support
Customizable axes for data
- Control viewable data window with axis ranges
- Customize value axis grid lines and labels with axis formatters
- Polar horizontal axes support for surface and scatter graphs
Customizable input handling
Customizable themes
Custom items and labels can be added to any graph
Ready-made data proxies to visualize data from Qt item models and height maps
Perspective and orthographic projections
Volumetric custom items

Getting Started

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

import QtDataVisualization 1.2

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

See the Getting started page for further information on how to use Qt Data Visualization in your application.
