It would be better to capture the lines are they are created rather than using ax.get_lines(),

lines = [l0, l1, l2]


# Make checkbuttons with all plotted lines with correct visibility
rax = plt.axes([0.05, 0.4, 0.1, 0.15])
check = CheckButtons(rax, ('2 Hz', '4 Hz', '6 Hz'), (False, True, True))
labels = [str(line.get_label()) for line in lines]
visibility = [line.get_visible() for line in lines]
check = CheckButtons(rax, labels, visibility)


def func(label):
if label == '2 Hz':
l0.set_visible(not l0.get_visible())
elif label == '4 Hz':
l1.set_visible(not l1.get_visible())
elif label == '6 Hz':
l2.set_visible(not l2.get_visible())
index = labels.index(label)
lines[index].set_visible(not lines[index].get_visible())
plt.draw()

check.on_clicked(func)

plt.show()
