Hi I have a numpy array
a = np.random.uniform(0,1, size = (10,3))
I want to plot each of the columns with its own label
plt.plot(a, label = ['label1', 'label2', 'label3'])
plt.legend()
How can I do that? The above is my tentative, but didn't work.
A slightly shorter approach (because the handles are already present in the legend):
import numpy as np
import matplotlib.pyplot as plt
a = np.random.uniform(0,1, size = (10,3))
plt.plot(a)
plt.legend(['label1', 'label2', 'label3'])
plt.show()
I think I found it here
l1,l2, l3 = plt.plot(a)
plt.legend((l1,l2, l3), ('label1', 'label2', 'label3'))
