in Ipython notebook / Jupyter, Pandas is not displaying the graph I try to plot

Edit:Pylab has been deprecated please see the current accepted answer

Ok, It seems the answer is to start ipython notebook with --pylab=inline. so ipython notebook --pylab=inline This has it do what I saw earlier and what I wanted it to do. Sorry about the vague original question.

simple after importing the matplotlib you have execute one magic if you have started the ipython as like this

ipython notebook 

%matplotlib inline 

run this command everything will be shown perfectly

With your import matplotlib.pyplot as plt just add

plt.show()

and it will show all stored plots.

Note that --pylab is deprecated and has been removed from newer builds of IPython, The recommended way to enable inline plotting in the IPython Notebook is now to run:

%matplotlib inline
import matplotlib.pyplot as plt
