示例1: pylab_setup
# 需要導入模塊: from matplotlib import backend_bases [as 別名]
# 或者: from matplotlib.backend_bases import _Backend [as 別名]
def pylab_setup(name=None):
"""
Return new_figure_manager, draw_if_interactive and show for pyplot.
This provides the backend-specific functions that are used by pyplot to
abstract away the difference between backends.
Parameters
----------
name : str, optional
The name of the backend to use. If `None`, falls back to
``matplotlib.get_backend()`` (which return :rc:`backend`).
Returns
-------
backend_mod : module
The module which contains the backend of choice
new_figure_manager : function
Create a new figure manager (roughly maps to GUI window)
draw_if_interactive : function
Redraw the current figure if pyplot is interactive
show : function
Show (and possibly block) any unshown figures.
"""
# Import the requested backend into a generic module object.

# Create a local Backend class whose body corresponds to the contents of
# the backend module. This allows the Backend class to fill in the missing
# methods through inheritance.

# Need to keep a global reference to the backend for compatibility reasons.
