标签未出现在 Seaborn distplot 中

Question

I am using the distplot() function of Seaborn and I am juxtaposing two density plots -- each with a different color in the same plot -- and I want to label them.

I use the argument 'label', referred in the documentation of the function.

My code is:

Response4_mask = train_with_response['Response4'] == 1
not_Response4_mask = train_with_response['Response4'] != 1

plt.figure()

sns.distplot(a = train_imp_with_response[Response4_mask]['Family_Hist_4'], hist = True, color = 'red', label = 'Response4')
sns.distplot(a = train_imp_with_response[not_Response4_mask]['Family_Hist_4'], hist = True, label = 'not_Response4')

plt.title('Family_Hist_4')

plt.tight_layout()
plt.show()

The output is below. There is no label in it:

Just add

plt.legend()

See documentation for legend() and matplotlib's legend guide for more details

before plt.show()
