Hi! I gave it a try but still same result. I uninstalled everything with
sudo pip3 uninstall pyqtgraph and made sure that under dist-packages there was nothing left. Then I tried to download it from source forge but with no much success, finally, as is read here https://github.com/pyqtgraph/pyqtgraph , I used the command: pip install git+https://github.com/pyqtgraph/pyqtgraph@develop or, actually, sudo pip3 install git+https://github.com/pyqtgraph/pyqtgraph@develop Any other idea of what I could try?
