Graphic line plot with matplotlib, text file in pytho

[khadija]

hello, I want to display a graph using data from a text file with matplotlib and I am having some problems. Data is sent and received via sockets and stored in a text file.

here is my code:

import matplotlib.pyplot as plt



X = []
Y = []




fichier = open('orde.txt', 'r')


for row in fichier:
    row=row.split(' ')
    if len(row)>0:
     X.append(row[0])
     Y.append(row[-1])



plt.xlabel('Time' , fontsize = 12)
plt.ylabel('Amplitude', fontsize = 12)
plt.plot(X, Y ,color = 'red', label = 'signal')

plt.title('Courbe', fontsize = 20)
plt.show()
