Use of plt.legend()

#1

why do we use plt.legend() ?

#2

hey @muditarya31 ,
while we plot more than 1 number of lines on a matplotlib plot , the module understands and make them with different colors to help in distinguish.
But , there are many lines assume 5 ,then even with different colors we don’t know which color responds to which value.
Hence, for this we use plt.legend() . It creates a small rectangle showing what color line is used for which value.

I hope this would have helped you understand plt.legend()

Thank You and Happy Learning :slightly_smiling_face:.
