bonjours 

je suis en train de travailler sur un projet le but de ce projet c'est affichee les valeur des 4 capteur sur 4 graph (live plot)

le probleme que je rencontre c'est que je veux affiché  proche de chaque point sont valeur 

voila un exemple

voila mon code :

import serial # import Serial Library
import time #import time 
import numpy  # Import numpy
import matplotlib.pyplot as plt #import matplotlib library
from drawnow import *


temperature= []
vitesse= []
charge= []
current= []

arduinoData = serial.Serial('com5', 9600) #Creating our serial object named arduinoData
plt.ion() #Tell matplotlib you want interactive mode to plot live data
cnt=0


def makeFig(): #Create a function that makes our desired plot
    
    plt.subplot(2,2,1)
    plt.title('Live Streaming Temperature Sensor Data')
    plt.ylabel('Temperature C')
    plt.grid(True)
    plt.plot(temperature, 'ro-')
                
    plt.subplot(2,2,2)
    plt.title('Live Streaming Speed Sensor Data')
    plt.ylabel('Speed KM/H')
    plt.grid(True)
    plt.plot(vitesse, 'bo-')

    plt.subplot(2,2,3)
    plt.title('Live Streaming SOC Sensor Data')
    plt.ylabel('Battery Charge %')
    plt.grid(True)
    plt.plot(charge, 'go-')

    plt.subplot(2,2,4)
    plt.title('Live Streaming Current Sensor Data')
    plt.ylabel('Current A')
    plt.grid(True)
    plt.plot(current, 'yo-')
    



while True: # While loop that loops forever
    while (arduinoData.inWaiting()==0): #Wait here until there is data
        pass #do nothing
    arduinoString = arduinoData.readline() #read the line of text from the serial port
    dataArray = arduinoString.split(';')   #Split it into an array called dataArray
    temp = float (dataArray[0])
    vite = float (dataArray[1])
    char = float (dataArray[2])
    curr = float (dataArray[3])
    temperature.append(temp)                     #Build our temperature array by appending temp readings
    vitesse.append(vite)                     #Build our vitesse array by appending temp readings
    charge.append(char)                     #Build our charge array by appending temp readings
    current.append(curr)                     #Build our current array by appending temp readings
    drawnow(makeFig)                       #Call drawnow to update our live graph
    plt.pause(0.00001)
    cnt=cnt+1
    if(cnt>50):
        temperature.pop(0)
        vitesse.pop(0)
        charge.pop(0)
        current.pop(0)
    
    
    

est ce qu'il ya des idées ou des suggestion
