"""A file contains N columns of values, describing N–1 curves. The first column contains the x coordinates, the second column contains the y coordinates of the first curve, the third column contains the y coordinates of the second curve, and so on. We want to display those N–1 curves. We will do so by using the following code:
"""
import numpy as np
import matplotlib.pyplot as plt
data = np.loadtxt('my_data1.txt')
for column in data.T:
	#метод .T транспонирует матрицу
	plt.plot(data[:,0], column)
plt.show()
