copied!<p>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.</p> <pre><code>#!/usr/bin/python # _*_ coding: utf8 _*_ 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() </code></pre> <p>I did not find any other topic on a file based drawing.</p>
