motion_notify_event from backend_kivy.py is not found?

[chrisInTheCode]

Hi! I am relatively newer to python (and certainly kivy and matplotlib) and am working on a project. I am trying to use a matplotlib graph within kivy, which seems like it works fine - except for that I'm getting an internal error inside of kivy matplotlib backend that I cannot trace back to my own code.

Here is the error I am getting:

kivy\garden\matplotlib\backend_kivy.py", line 1204, in _on_mouse_pos self.motion_notify_event(x, y, guiEvent=None) ^^^^^^^^^^^^^^^^^^^^^^^^ AttributeError: 'FigureCanvasKivyAgg' object has no attribute 'motion_notify_event'. Did you mean: 'enter_notify_event'?

Now, if I try to trace back and find motion_notify_event, the farthest back I can get is the _on_mouse_pos() method within backend_kivy.py. It seems to have a definition for leave_notify_event and enter_notify_event, but not one for motion_notify_event. There are several references throughout backend_kivy.py, but I cannot find where it ever provides a definition for how to handle it.

Is this a known bug within backend_kivy? Am I just missing something on my side to handle this myself? I know this is not much to go on, so just let me know what else I need to provide. I can't trace it back to anywhere in my code and it is unreasonable to put the entire project here. Thanks for any help or ideas!

Would be the matplotlib version, could leave to recipe default (3.5.4), use a version prior to 3.8.0 or alter this repo to support it.

At the moment, kivy matplotlib garden is not compatible with matplotlib 3.8. As an alternative, you can use my library if you want. For interactive graph it is much faster. https://github.com/mp-007/kivy_matplotlib_widget.

Also, like @HyTurtle say, the android recipe is set to 3.5.4.

Thanks for the info! Will try some things out.

Thanks for the info and library, I'll check it out. Thanks!

Wait. Your are already using my library (kivy-matplotlib-widget==0.6.1) ?? Please don't use kivy garden matplotlib at the same time. It's 2 differents libraries.

If you have an code example. I can certainly help you (ask on kivy discord or in my github repo).

Please note they are migrating to this repo:
https://github.com/kivy-garden/matplotlib

to be more consistent with the modern garden format.

Please note this existing issue:
kivy-garden/matplotlib#1

Also note that the Android and iOS recipes are in the 3.7 series, and updating them is not easy. I contributed the iOS recipe for matplot 3.7.5. I assume the garden recipe and the recipes would need to be synchronized.
