Module: core.pylabtools¶
Pylab (matplotlib) support utilities.
10 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 the argument list contains references to invalid figures, a warning is printed but 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', **kwargs)¶ Print a figure to an image, and return the resulting file data
Returned data will be bytes unless
fmt='svg', in which case it will be unicode.Any keyword args are passed to fig.canvas.print_figure, such as
qualityorbbox_inches.
-
IPython.core.pylabtools.retina_figure(fig, **kwargs)¶ format a figure as a pixel-doubled (retina) PNG
-
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 the safe_execfile()method of IPython.Returns: - A function suitable for use as the
runnerargument of the %run magic - function.
- A function suitable for use as the
-
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 or set) – 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’).
- 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 (//ipykernel.pylab.backend_inline’).)
-
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)
-
IPython.core.pylabtools.configure_inline_support(shell, backend)¶ Configure an IPython shell object for matplotlib use.
Parameters: - shell (InteractiveShell instance) –
- backend (matplotlib backend) –
