PyQtGraph

A pure-Python graphics library for PyQt5/PyQt6/PySide2/PySide6

Copyright 2024 PyQtGraph developers

https://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

PyQtGraph has adopted NEP 29.

This project supports:

• All minor versions of Python released 42 months prior to the project, and at minimum the two latest minor versions.
• All minor versions of numpy released in the 24 months prior to the project, and at minimum the last three minor versions.
• Qt5 5.15, and Qt6 6.2+

Currently this means:

• Python 3.10+
• Qt 5.15, 6.2+
• PyQt5, PyQt6, PySide2, or PySide6
• numpy 1.24+

Optional added functionalities

Through 3rd part libraries, additional functionality may be added to PyQtGraph, see the table below for a summary.

Library	Added functionality
scipy	Image processing through ndimage Data array filtering through signal
pyopengl	3D graphics Faster image processing
h5py	Export in hdf5 format
colorcet	Add a collection of perceptually uniform colormaps
matplotlib	Export of PlotItem in matplotlib figure Add matplotlib collection of colormaps
cupy	CUDA-enhanced image processing Note: On Windows, CUDA toolkit must be >= 11.1
numba	Faster image processing
jupyter_rfb	Jupyter Notebook support
