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

|
|
|
|
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](https://numpy.org/neps/nep-0029-deprecation_policy.html).
|
|
|
|
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.
|
|
* All Qt5 versions from 5.12-5.15, and Qt6 6.1
|
|
|
|
Currently this means:
|
|
|
|
* Python 3.7+
|
|
* Qt 5.12-5.15, 6.1
|
|
* Required
|
|
* [PyQt5](https://www.riverbankcomputing.com/software/pyqt/), [PyQt6](https://www.riverbankcomputing.com/software/pyqt/), [PySide2](https://wiki.qt.io/Qt_for_Python) or [PySide6](https://wiki.qt.io/Qt_for_Python)
|
|
* [`numpy`](https://github.com/numpy/numpy) 1.17+
|
|
|
|
