python - How to get started/use matplotlib in kivy

Question

I have recently learned a bit of matplotlib and would like to use it within kivy. I have read a little documentation on the garden here and there but don't really understand it. I have installed kivy garden and matplotlib but don't know how to proceed from here. I simply want to add a already completed matplotlib graph into kivy. I would appreciate a step by step simplified set of instructions of how to get what I already coded into kivy and get it to display. Thanks

Here is the simplest example possible for kivy-garden matplotlib and kivy. If you would like to do more advanced things, check out their examples: https://github.com/kivy-garden/garden.matplotlib/tree/master/examples I think it should be enough to get you started with your plot.

Below I am adding it to a BoxLayout, you can add more widgets to this BoxLayout or add this BoxLayout somewhere else.

python code example.py:

from kivy.garden.matplotlib.backend_kivyagg import FigureCanvasKivyAgg
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
import matplotlib.pyplot as plt

plt.plot([1, 23, 2, 4])
plt.ylabel('some numbers')

class MyApp(App):

    def build(self):
        box = BoxLayout()
        box.add_widget(FigureCanvasKivyAgg(plt.gcf()))
        return box

MyApp().run()
