Perhaps you are using garden with the old method?

Some reading:

https://kivy.org/doc/stable/api-kivy.garden.html

I get

ERROR: Could not find a version that satisfies the requirement kivy_garden.matplotlib (from versions: none)
ERROR: No matching distribution found for kivy_garden.matplotlib

It seems garden.matplot lib has not been updated. I did not understand this.

Any reason you don't use matplotlib directly?

No idea about the old way.
