[Matplotlib-users] Matplotlib Figure margin transparancy

It appears that jupyter does not use the .ipython_config.py file in the .jupyter directory. It does use the files in the profile_default directory in your ipython folder, usually ~/.ipython on a Mac. Here's how I was able to get jupyter qtconsole to launch with %pylab inline
Create the default ipython profile files. I think this will overwrite any old default profile files so make a backup if you want to keep the old files
$ ipython3 profile create
Find the location of your default profile
$ export myipython=$(ipython3 locate profile)
Edit the ipython_config.py file in your default profile directory
$ pico "$myipython"/ipython_config.py
Uncomment the c.InteractiveShellApp.pylab line and change the value to 'inline'
If want to load certain modules every time you launch qtconsole you can create a file named something like 00_my_startup.ipy in "$myipython"/startup/ containing your imports. See the "$myipython"/startup/README file for more info
Here's the docs on configuring recent versions of ipython
http://ipython.readthedocs.io/en/stable/config/intro.html#the-ipython-directory
Best regards,
Scott

There is no apparent effect for facecolor parameter. May I know which parameter sets the margin as non-transparent?

I think they have changed the default a couple of times and had the transparent as a default earlier but changed it. Looking at the current master it looks like they are respecting the matplotlib default colors from the matplotlib rc params. Can you please check which version on IPython and Jupyter you are running.
