Plot into Tkinter

[carloszoom3000]

Hi,

I'm plotting a signal from an Arduino analog pin.
I'm able to plot it, however i cannot get to embed it into a tkinter window.
All i get is separated windows, one for the plot and another for tkinter.

import serial
import time
import csv
import matplotlib
matplotlib.use("tkAgg")
import matplotlib.pyplot as plt
import numpy as np
from time import perf_counter 
import tkinter as tk 
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
from matplotlib.figure import Figure

root = tk.Tk()
fig = Figure()
ax = fig.add_subplot(111)
# ax = plt.axes(xlim=(0,100),ylim=(120,150)); #displaying only 100 samples
ax.set_title('Serial Data')
ax.set_xlabel('Sample')
ax.set_ylabel('Pot1')
ax.set_xlim(0, 100)
ax.set_ylim(50, 1000)
ax.grid()
lines = ax.plot([], [])[0]
canvas = FigureCanvasTkAgg(fig, master=root)  # A tk.DrawingArea.
canvas.get_tk_widget().place(x=20, y=20, width=600, height=600)
canvas.draw()



ser = serial.Serial('COM4')
ser.flushInput()

plot_window = 20
y_var = np.array(np.zeros([plot_window]))

plt.ion()
fig, ax = plt.subplots()
line, = ax.plot(y_var)

while True:
    try:
        ser_bytes = ser.readline()
        try:
            decoded_bytes = float(ser_bytes[0:len(ser_bytes)-2].decode("utf-8"))
            print(decoded_bytes)
        except:
            continue
        with open("test_data.csv","a") as f:
            writer = csv.writer(f,delimiter=",")
            writer.writerow([time.perf_counter(),decoded_bytes])
        y_var = np.append(y_var,decoded_bytes)
        y_var = y_var[1:plot_window+1]
        line.set_ydata(y_var)
        ax.relim()
        ax.autoscale_view()
        fig.canvas.draw()
        fig.canvas.flush_events()
    except:
        print("Keyboard Interrupt")
        break


root.mainloop()

i appreciate your help.

Regards,
