PyQtGraph

Upcoming changes will involve removing PySide2 support (No plans to remove PyQt5 support for the time being).

If you are seeing this, have some #OpenGL programming experience and would like to contribute to #PyQtGraph, please reach out!

Do you use pg.ConsoleWidget and have some preference for it over #IPython ‘s QtConsole? If so I’d like to hear from you. We’re considering deprecating ConsoleWidget and directing users to use the Jupyter/IPython QtConsole instead.

Do you use #PyQtGraph with conda versions of #PySide bindings? Then this issue is very relevant to you. Please upvote:

The next release of #PyQtGraph will likely be the last release to support PySide2. If this will impact you negatively, please reach out.

We have recently merged into the repo a new on of #OpenGL related improvements, mostly for 3D, but PColorMeshItem got some love too. If you use #PyQtGraph for 3D visualization, we’d love to hear back from you.

Lastly, for #PyQtGraph developers, we now have stub files for getting auto-completion when using pyqtgraph.Qt, which is PyQtGraph's Qt abstraction layer. This layer is not intended to be used outside of #PyQtGraph, if you want a Qt abstraction layer for your project, we recommend the #QtPy library.

We have had a stub file there for a while, but it only worked in PyCharm, the stubs now work with pyright and PyCharm now.

#PyQtGraph 0.13.5 is out! While not our largest release, it has something for everyone! Note, this release is the last to support #Python
3.9 and #NumPy 1.22.

First, ImageItem got another substantial performance boost, especially if you're using #numba but there is a significant boost for #NumPy users as well.

A ColorMapMenu was added to ColorBarItem, allowing for users to be able to change color maps interactively instead of programmatically.

@fluiddyn The #PIV image case would be a good one for #PyQtGraph, given our origins of working with 2D slices of “3D images". Please don't hesitate to reach out if you could use assistance with plotting or trying to improve performance.
