plt.legend() only shows the first letter of the legend string

In the following code the legend should be the names specified in the list, but as you can see in the figure, only the first letter is shown.

bench = ['AA', 'BB']
offset = 0
for b in bench:
    L1 = [12+offset, 5+offset, 3+offset]
    L2 = [20+offset, 22+offset, 25+offset]
    offset += 5
    
    plt.plot(L1, L2)
    plt.legend(b)
    plt.savefig('test4.png')
    plt.show()

enter image description here

How can I fix that?

plt.legend() takes an iterable of labels, so if you only need the label with everything else unchanged, you can replace

plt.legend(b)

with

plt.legend([b])

You have used legend not properly and you need to use the label argument.

import matplotlib.pyplot as plt

bench = ['AA', 'BB']
offset = 0
for b in bench:
    L1 = [12+offset, 5+offset, 3+offset]
    L2 = [20+offset, 22+offset, 25+offset]
    offset += 5
    
    plt.plot(L1, L2, label=b)
    plt.legend()
    plt.savefig('test4.png')
    plt.show()
