There is altarnative way to display any matplotlib graph in Kivy. Use python self module io() like,

from kivy.app import App
from kivy.uix.button import Button
from kivy.uix.widget import Widget
from kivy.uix.label import Label
from kivy.lang.builder import Builder
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.image import Image,CoreImage      #for create a image with coreimage

import io   #I used io it's simple and useful!

import matplotlib.pyplot as plt   #need matplotlib library

kivy=Builder.load_string("""

<Image_Example>:

    BoxLayout:
        orientation:'vertical'
   
        Button:
            id:click
            text:'display image'
            on_press:root.display_img()  #when it click display image
        Label:
            text:'That is your image'

        Image:
            id:img
            source:''  #image source
           
            allow_stretch:True
           
            keep_ratio:True

""")

class Image_Example(BoxLayout):

    def display_img(self):
        X=[ 1, 2, 3, 4, 5]
        Y= [5, 14, 7, 20, 11]  #your dataset
       
        plt.plot(X,Y)  #craete yourdataset graph
        plt.title("title here")
        plt.xlabel("x-axis label here)")
        plt.ylabel("y-axis label here")
       
        buf=io.BytesIO()
        plt.savefig(buf)  #save your dataset to IoByte
       
        buf.seek(0) #seek your graph
        self.ids.img.texture=CoreImage(buf, ext="png").texture     #display your image
        self.ids.img.reload()
        del buf #then delete created buf

class ImageApp(App):
    def build(self):
        return Image_Example()
       

kv=ImageApp().run()

If I were you, I would clone "https://github.com/kivy-garden/garden.matplotlib" to the "virt(directory with your virtual environment)/lib/python/kivy/garden/" "git clone https://github.com/kivy-garden/garden.matplotlib" and rename the directory "garden.matplotlib" to the "matplotlib"
