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

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
|
|
------------
|
|
|
|
* PyQt 4.8+, PySide, PyQt5, or PySide2
|
|
* PySide2 5.14 does not have loadUiType functionality, and thus the example application will not work. You can follow along with restoring that functionality [here](https://bugreports.qt.io/browse/PYSIDE-1223).
|
|
* Python 2.7, or 3.x
|
|
* Required
|
|
* `numpy`
|
|
* Optional
|
|
* `scipy` for image processing
|
|
* `pyopengl` for 3D graphics
|
|
* macOS with Python2 and Qt4 bindings (PyQt4 or PySide) do not work with 3D OpenGL graphics
|
|
* `pyqtgraph.opengl` will be depreciated in a future version and replaced with `VisPy`
|
|
* `hdf5` for large hdf5 binary format support
|
|
* Known to run on Windows, Linux, and macOS.

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