PyQtGraph

A pure-Python graphics library for PyQt/PySide/PyQt5/PySide2

http://www.pyqtgraph.org

PyQtGraph is intended for use in mathematics / scientific / engineering applications. Despite being written entirely in python, the library is fast due to its heavy leverage of numpy for number crunching, Qt's GraphicsView framework for 2D display, and OpenGL for 3D display.

Requirements

Python 2.7, or 3.x
Required
- PyQt 4.8+, PySide, PyQt5, or PySide2
- numpy
Optional
- scipy for image processing
- pyopengl for 3D graphics
- hdf5 for large hdf5 binary format support

Qt Bindings Test Matrix

The following table represents the python environments we test in our CI system. Our CI system uses Ubuntu 18.04, Windows Server 2019, and macOS 10.15 base images.

Qt-Bindings	Python 2.7	Python 3.6	Python 3.7	Python 3.8
PyQt-4	✅	❌	❌	❌
PySide1	✅	❌	❌	❌
PyQt5-5.9	❌	✅	❌	❌
PySide2-5.13	❌	❌	✅	❌
PyQt5-Latest	❌	❌	❌	✅
PySide2-Latest	❌	❌	❌	✅

pyqtgraph has had some incompatibilities with PySide2 versions 5.6-5.11, and we recommend you avoid those versions if possible
on macOS with Python 2.7 and Qt4 bindings (PyQt4 or PySide) the openGL related visualizations do not work reliably
