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

Question

I am trying to plot some data using pandas in Ipython Notebook, and while it gives me the object, it doesn't actually plot the graph itself. So it looks like this:

In [7]:

pledge.Amount.plot()

Out[7]:

<matplotlib.axes.AxesSubplot at 0x9397c6c>

The graph should follow after that, but it simply doesn't appear. I have imported matplotlib, so that's not the problem. Is there any other module I need to import?

I was able to plot things a couple days ago, while following a video,but now I can't seem to plot anything. and I seem to be doing the same thing as the documentation. http://pandas.pydata.org/pandas-docs/stable/visualization.html So I figure something with my system is wrong or a module isn't imported — chrisfs, May 09 '12 at 07:00
@chrisfs there is a newer correct answer. The one you selected a few years ago is now incorrect. Will you consider changing your accepted answer? Thanks. — tumultous_rooster, Jul 02 '15 at 17:48

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

See this post from the ipython-dev mailing list for more details.

Very good. After using `%matplotlib inline` my attempts to plot resulted in inline visible image, nice. In fact, the import is not necessary if the plot is method of already existing object like in OP. – Jan Vlcinsky Feb 25 '15 at 23:03

This is the new correct answer. More info [in this blog post](http://nbviewer.ipython.org/github/Carreau/posts/blob/master/10-No-PyLab-Thanks.ipynb). – Scott Lowrey Apr 15 '15 at 17:21
@Tal Yarkoni I added first line of your answer so that it worked. thanks~~! – verystrongjoe Feb 13 '17 at 02:33
Also applies to pandas in Jupyter notebook. – datalifenyc Feb 21 '17 at 00:58
For completeness sake, `%matplotlib nbagg` is useful these days to get a more interactive version. – Frederick Nord Apr 07 '18 at 14:20
@FrederickNord It failed to display with nbagg. – Asclepius Sep 27 '18 at 21:19

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.

Yes, that's what you need. You can also run `%pylab inline` inside a notebook to enable pylab mode. – Thomas K May 10 '12 at 11:52

note that it does not have to be in inline mode though for pandas to work. I am happily using just `ipython notebook --pylab` with pandas to have the plot in an extra window, if that's what someone wants. – K.-Michael Aye Dec 18 '12 at 20:22

With your import matplotlib.pyplot as plt just add

plt.show()

and it will show all stored plots.

ok that helps. I thought Ipython would do inline plots automatically. The documentation for pandas also doesn't show having to do plt.show() http://pandas.pydata.org/pandas-docs/stable/visualization.html – chrisfs May 09 '12 at 07:03

Yes, that was the first answer on this question, but it also seems to be deprecated now. – chrisfs Feb 01 '15 at 07:57

All you need to do is to import matplotlib.

import matplotlib.pyplot as plt
