Matplotlib backend nbagg does not show figure in iPython Notebook

Hmm, that should work. I notice that you are using the beta 3.0 ipython release. Perhaps something is broken in the beta? Could you try downgrading ipython (and the notebook server, they are separate packages, I think)?

I’m running the ipython server on a remote linux machine and using chrome browser on my windows 7 desktop.

I start the notebook with :

ipython notebook --ip 0.0.0.0

I’ve tried this both inside and out of a virtualenv virtual environment with same results.

thanks.

How did you start ipython?

hi Benjamin

This sequence in a new notebook:

%matplotlib nbagg

import matplotlib as mpl

import matplotlib.pyplot as plt

plt.plot(range(100))

also results in exactly the same result - the figure placeholder (not sure what the exact term is) but no figure inside it.

Regards.

Selecting a backend must be first before any other matplotlib actions. Typically, ipython magics (the %matplotlib commands) are kept at the top anyway.

I hope that clears it up.

Hello,

I’m running the following configuration

Python 2.7.6 (default, Feb 5 2015, 00:21:43)

IPython 3.0.0-b1

matplotlib ‘1.4.2’

The version of the notebook server is 3.0.0-b1-ee6223a.

This is running on linux 3.16.0-0.bpo.4-amd64 #1 SMP Debian

3.16.7-ckt2-1~bpo70+1 (2014-12-08) x86_64 GNU/Linux

I set up matplotlib as follows:

import matplotlib as mpl

import matplotlib.pyplot as plt

%matplotlib nbagg

Then running this command:

plt.plot(range(100))

only displays a box (with resize, zoom, pan, etc controls) - but does not

show the figure itself (see figure).

<http://matplotlib.1069221.n5.nabble.com/file/n44812/Untitled.png>

Also, when I click on any part of the figure, I get a slew of the following

message on stderr:

[IPKernelApp] ERROR | No such comm: 29281512bed24f259572bc6f0ea8d249

On the other hand,

plt.plot(range(100))

plt.show()

shows nothing at all.

However, this

%matplotlib inline

plt.plot(range(100))

displays the figure as expected.

What is going on ? How can I enable the new notebook backend for matplotlib

?

Thanks.
