PyQtGraph
A pure-Python graphics library for PyQt5/PyQt6/PySide6
Copyright 2025 PyQtGraph developers
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.

PyQtGraph has adopted SPEC 0.
This project supports:
- Python versions released within the last 3 years
- NumPy, SciPy and matplotlib versions released within the last 2 years
- Qt5 5.15 or Qt6 6.8+
Currently this means:
