Plot won't show in Jupyter

I’m new to python and I began to teach myself how to use pandas on jupyter using the exercise from this link:

http://nbviewer.jupyter.org/github/jvns/pandas-cookbook/blob/v0.1/cookbook/Chapter%201%20-%20Reading%20from%20a%20CSV.ipynb

I have the problem that the plot at 1.3 won’t appear when I do it in Jupyter, I only get the following output:

matplotlib.axes._subplots.AxesSubplot at 0x8ad24a8>"

However it does appear when I run the same code in Spyder. Does anyone know why this is? This is my code:

 import pandas as pd
import os
fixed_df = pd.read_csv('bikes.csv', sep=';', encoding='latin1', parse_dates=['Date'], dayfirst=True, index_col='Date')
fixed_df['Berri1'].plot()
