This function lets you activate matplotlib interactive support
at any point during an IPython session. It does not import anything
into the interactive namespace.
If you are using the inline matplotlib backend in the IPython Notebook
you can set which figure formats are enabled using the following::
In [1]: from IPython.display import set_matplotlib_formats
In [2]: set_matplotlib_formats('pdf', 'svg')
The default for inline figures sets `bbox_inches` to 'tight'. This can
cause discrepancies between the displayed image and the identical
image created using `savefig`. This behavior can be disabled using the
`%config` magic::
In [3]: %config InlineBackend.print_figure_kwargs = {'bbox_inches':None}
In addition, see the docstring of
`IPython.display.set_matplotlib_formats` and
`IPython.display.set_matplotlib_close` for more information on
changing additional behaviors of the inline backend.
Examples
--------
To enable the inline backend for usage with the IPython Notebook::
In [1]: %matplotlib inline
In this case, where the matplotlib default is TkAgg::
In [2]: %matplotlib
Using matplotlib backend: TkAgg
But you can explicitly request a different GUI backend::
In [3]: %matplotlib qt
You can list the available backends using the -l/--list option::
In [4]: %matplotlib --list
Available matplotlib backends: ['osx', 'qt4', 'qt5', 'gtk3', 'gtk4', 'notebook', 'wx', 'qt', 'nbagg',
'gtk', 'tk', 'inline']

This function lets you activate pylab (matplotlib, numpy and
interactive support) at any point during an IPython session.
%pylab makes the following imports::
import numpy
import matplotlib
from matplotlib import pylab, mlab, pyplot
np = numpy
plt = pyplot
from IPython.display import display
from IPython.core.pylabtools import figsize, getfigs
from pylab import *
from numpy import *
If you pass `--no-import-all`, the last two `*` imports will be excluded.
See the %matplotlib magic for more details about activating matplotlib
without affecting the interactive namespace.
