Aula 2 plotando o grafico

Segui os passos da professora, e até colei o codigo direto da transcrição, mas sempre sai esse erro:

ImportError                               Traceback (most recent call last)

   1798     return module

ImportError: matplotlib is required for plotting when the default backend "matplotlib" is selected.

Tentei importar o matplotlib e depois correr o codigo de novo, sem sucesso.
