Creating an oval inside a pyplot in Tkinter window

[Tafla Magnaw]

      I spent about a week solving the problem I have in this code but I couldn't do anything. I just give up working due to that line of code.
 
         What I need is that: 
I have a main window with an "oval menu bar" and under the menu-bar, there is a " Add Oval" drop-down menu. when I click the "Add oval" drop-down menu, a pop up window with entry boxes will display.Enter the x & y location (for example 50 &150 and click the send button, the oval should display inside of the left side pyplot. The code below works fine with tkinter window but not working with in the pyplot. How can I create the oval inside the left side of the pyplot? I spent long time to figure out that but I couldn't do anything.I really need any help please.The only problem with the code below is on the App(tk.Tk) class.I really need any help please!! Thank you


             Here is the code I tried:

         

       
        from tkinter import *
        from tkinter import Tk, Frame, Entry, Button, 
        Listbox,StringVar,Label,Menu,filedialog, END
        from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
        import tkinter as tk
        from matplotlib.figure import Figure
        import matplotlib.gridspec as gridspec

        root = tk.Tk()
        RADIUS = 10
        root.title("Oval window")
        fig = Figure(figsize=(10,10))
        gs = gridspec.GridSpec(1, 2)
        ax1 = fig.add_subplot(gs[0, 0])
        ax1.set_xticks([])
        ax1.set_xticklabels([])
        ax1.set_yticks([])
        ax1.set_yticklabels

        gs = gridspec.GridSpec(2, 2)
        ax2 = fig.add_subplot(gs[0, 1])

        ax2.set_xticks([])
        ax2.set_xticklabels([])
        ax2.set_yticks([])
        ax2.set_yticklabels

        gs = gridspec.GridSpec(2, 2)
        ax3 = fig.add_subplot(gs[1, 1])
        ax3.set_xticks([])
        ax3.set_xticklabels([])
        ax3.set_yticks([])
        ax3.set_yticklabels

        canvas = FigureCanvasTkAgg(fig, master=root)
        canvas.get_tk_widget().pack(side=tk.TOP, fill=tk.BOTH, expand=1)
        canvas.get_tk_widget().pack()
        canvas.draw()
        fig.set_tight_layout({'rect': [0, 0, 0.996, 0.998], 'pad': 0.2, 'h_pad': 0.2})
        fig.set_facecolor( 'blue' )


        def Remove_entries():
            for field in fields:
              field.Remove(0,END) 


        def enter_values():

            nw = Toplevel()
            nw.title(" Removing Oval")

            Remove_button = Button(nw, text=" Remove", command=Remove_entries)

            Remove_button.pack() 

            Button1 = Button(nw, text=" Cancel",command=nw.destroy) 
            Button1.pack()
            TheListBox = Listbox(nw) # Add a list entry widget
            TheListBox.pack() 
            for item in ["oval1", "oval2", "oval3", "oval4","SS5","oval6....","ovaln"]: # add four items to the listbox from the main window
                TheListBox.insert(END, item)
