Additional context
my project: "Audio waveform generator with other audio editing functionalities for a client"
been stuck since 4 days, tried with
kivy.garden.matplotlib then later found out not using that anymore and shifted to this
then read some docs and comments
found out about kivy_matplotlib_widget (thats malfunctioning as well in my project)
toolbar buttons not properly binded
and now i'm trying out this part.. need help if anyone has solved this?
saw that someone pushed to pypi
do i need to update my python version ?
