I am fairly new in python, and I am trying to have a plot, based on data stored in a file. This file may be updated at any time, so I am trying to make the drawing updated every 3 seconds (so I don't use all the CPU). My problem is that the GUI freezes after the lunch.

import matplotlib.pyplot as plt
import numpy as np
import time
plt.ion()
plt.figure()
i=0
while 1:
taille=0
fichier=np.loadtxt('data/US.SAVE')
fichier1=np.loadtxt('data/cond.SAVE')
taille1=np.size(fichier1[:,1])
taille=np.size(fichier[:,1])
min=min(fichier[0,0],fichier1[0,0]);
fichier[:,0]=fichier[:,0]-min
fichier1[:,0]=fichier1[:,0]-min
if (taille != taille1) :
printErrors("TAILLE DE FICHIERS DIFFERENTES")
nb_chunks=np.size(fichier1[1,:])
nb_inputs=np.size(fichier[1,:])
plt.subplot(3,1,1)
plt.bar(fichier[:,0],fichier[:,1],align='center',width=0.0001, facecolor='b', label="US")
x1,x2,y1,y2 = plt.axis()
x1=x1-0.0001
plt.axis([x1, x2, y1, 1.2])
plt.legend(ncol=3,prop={'size':9})
plt.title("US ")
plt.ylabel('Activation')
plt.xlabel('Time')
plt.subplot(3,1,2)
plt.bar(fichier1[:,0],fichier1[:,1],align='center',width=0.0001, facecolor='b', label="response")
plt.axis([x1, x2, y1, 1.2])
plt.legend(ncol=3,prop={'size':9})
plt.title("Response ")
plt.ylabel('Activation')
plt.xlabel('Time')
plt.subplot(3,1,3)
plt.bar(fichier[:,0]-fichier1[:,0],fichier1[:,1],align='center',width=0.0001, facecolor='b', label="Error")
plt.axis([x1, x2, y1, 1.2])
plt.legend(ncol=3,prop={'size':9})
plt.title("Error")
plt.ylabel('Activation')
plt.xlabel('Time')
plt.draw()
name1='data/Conditionnement.eps'
plt.savefig(name1,dpi=256)
plt.draw()
del fichier,fichier1,min
i=i+1
time.sleep(3)
plt.show()
I did not find any other topic on a file based drawing.
