Hi everybody! I'm designing a test bank than shows me 3 temperatures of a vacuum pump, the current of the motor than impulse that pump, the rpm of the vacuum pump, the KPa of the pump and i want to save all the data reading by the sensors in the test time in a txt archive at the same time I want to see all those values in a graphic interface in Python 3.7 and here start the headaches Big Grin

So i began with the 3 temperature values, for this i connected 3 termocuples to an Arduino UNO board and i made this code:

This is of course 'C' code, still looks better in 'Python' frame:
//This code sense 3 temperatures detected by Type "K" thermocuples

#include <max6675.h> //Librería del MAX6675

unsigned long interval=5000; //
unsigned long previousMillis=0; // 

int ktcSO = 8;
int ktcCS1 = 9; // Thermocuple 1
int ktcCLK = 10;
int ktcCS2 = 11; // Thermocuple 2
int ktcCS3 = 6; // Thermocuple 3

int temp1; //
int temp2; // 
int temp3; //
int contadordetiempo = 0; 

MAX6675 ktc1(ktcCLK, ktcCS1, ktcSO);
MAX6675 ktc2(ktcCLK, ktcCS2, ktcSO);
MAX6675 ktc3(ktcCLK, ktcCS3, ktcSO);

void setup() 
  {
  Serial.begin(9600); /
  }

void loop() 

  {
  unsigned long currentMillis = millis(); 
  if ((unsigned long)(currentMillis - previousMillis) >= interval)
    {
    contadordetiempo = contadordetiempo + 5; 
    Serial.print(contadordetiempo); //Esto lo imprime python


    Serial.print("\t"); 
    temp1 = ktc1.readCelsius();
    Serial.print(temp1)
  
    Serial.print("\t"); 

    temp2 = ktc2.readCelsius();
    Serial.print(temp2);
    
    Serial.print("\t");

    
    temp3 = ktc3.readCelsius();
    Serial.print(temp3);
   
  
    Serial.print("\n");  
    
    previousMillis = millis(); 
    }
  }
Then i design this code to watch my values in a graphic 

import serial
import time

import matplotlib.animation as animation
from tkinter import *
from matplotlib.axes import *

arduino= serial.Serial("COM6",9600)

	def guardardata(self):

		archivo.write("\nData Banco de prueba de bombas de vacío\n")
		archivo.write("Fecha: "+str(time.localtime()[2])+"-"+str(time.localtime()[1])+"-"+str(time.localtime()[0])+"\nHora: "+str(time.localtime()[3])+":"+str(time.localtime()[4])+"\n")

	def animada(self,i):
		
		
		while i<=200:	

			i += 1
			e = arduino.readline().decode("utf-8").strip("\n")
			s=e.split("\t")
			self.contador= s[0]
			self.temp1= s[1]
			self.temp2= s[2]
			self.temp3= s[3]

			self.t1.append(self.temp1)
			self.t2.append(self.temp2)
			self.t3.append(self.temp3)

			archivolectura.write(str(self.contador) +"\t"+ str(self.temp1) +"\t"+ str(self.temp2) +"\t"+ str(self.temp3) +"\n")
			
			#Para ver detalles en la shell 
			print("Temp 1 = " + self.temp1)
			print("Temp 2 = " + self.temp2)
			print("Temp 3 = " + self.temp3)
			print("Tiempo de prueba = " + self.contador)


			self.line1=plt.plot(self.tiempo, self.t1)
			self.line2=plt.plot(self.tiempo, self.t2)
			self.line3=plt.plot(self.tiempo, self.t3)

			plt.setp(self.line1, color='blue')
			plt.setp(self.line2, color='orange')
			plt.setp(self.line3, color='green')

			return self.line1, self.line2, self.line3

fase1.mainloop()
and when i run it shows me this İmage

and when i push the bottom "EMPEZAR" shows me this
İmage


And i want to plot my graph in my interface Cry by the way i can't put the axes limits in my graph (and that results into a complete disaster as seen in the second image)

i don't know how to do this i'm a newbie in Python Wall Doh if anybody coulds help me i'll be very grateful.
