9 Functions

IPython.core.pylabtools.getfigs(*fig_nums)

Get a list of matplotlib figures by figure numbers.

If no arguments are given, all available figures are returned. If theargument list contains references to invalid figures, a warning is printedbut the function continues pasting further figures.

Parameters:

figs (tuple) – A tuple of ints giving the figure numbers of the figures to return.

IPython.core.pylabtools.figsize(sizex,sizey)

Set the default figure size to be [sizex, sizey].

This is just an easy to remember, convenience wrapper that sets:

matplotlib.rcParams['figure.figsize']=[sizex,sizey]

IPython.core.pylabtools.print_figure(fig,fmt='png',bbox_inches='tight',base64=False,**kwargs)

Print a figure to an image, and return the resulting file data

Returned data will be bytes unlessfmt='svg',in which case it will be unicode.

Any keyword args are passed to fig.canvas.print_figure,such asquality orbbox_inches.

Ifbase64 is True, return base64-encoded str instead of raw bytesfor binary-encoded image formats

Added in version 7.29:base64 argument

IPython.core.pylabtools.retina_figure(fig,base64=False,**kwargs)

format a figure as a pixel-doubled (retina) PNG

Ifbase64 is True, return base64-encoded str instead of raw bytesfor binary-encoded image formats

Added in version 7.29:base64 argument

IPython.core.pylabtools.mpl_runner(safe_execfile)

Factory to return a matplotlib-enabled runner for %run.

Parameters:

safe_execfile (function) – This must be a function with the same interface as thesafe_execfile() method of IPython.

Returns:

• A function suitable for use as therunner argument of the %run magic

• function.

IPython.core.pylabtools.select_figure_formats(shell,formats,**kwargs)

Select figure formats for the inline backend.

Parameters:

• shell (InteractiveShell) – The main IPython instance.

• formats (str orset) – One or a set of figure formats to enable: ‘png’, ‘retina’, ‘jpeg’, ‘svg’, ‘pdf’.

• **kwargs (any) – Extra keyword arguments to be passed to fig.canvas.print_figure.

IPython.core.pylabtools.find_gui_and_backend(gui=None,gui_select=None)

Given a gui string return the gui and mpl backend.

Parameters:

• gui (str) – Can be one of (‘tk’,’gtk’,’wx’,’qt’,’qt4’,’inline’,’agg’).

• gui_select (str) – Can be one of (‘tk’,’gtk’,’wx’,’qt’,’qt4’,’inline’).This is any gui already selected by the shell.

Returns:

• A tuple of (gui, backend) where backend is one of (‘TkAgg’,’GTKAgg’,

• ’WXAgg’,’Qt4Agg’,’module (//matplotlib_inline.backend_inline’,’agg’).)

IPython.core.pylabtools.activate_matplotlib(backend)

Activate the given backend and set interactive to True.

IPython.core.pylabtools.import_pylab(user_ns,import_all=True)

Populate the namespace with pylab-related values.

Imports matplotlib, pylab, numpy, and everything from pylab and numpy.

Also imports a few names from IPython (figsize, display, getfigs)
