How do you determine which backend is being used by matplotlib?
Solution 1:
Use the get_backend() function to obtain a string denoting which backend is in use:
>>> import matplotlib
>>> matplotlib.get_backend()
'TkAgg'
Solution 2:
Another way to determine the current backend is to read rcParams dictionary:
>>> import matplotlib
>>> print (matplotlib.rcParams['backend'])
MacOSX
>>> matplotlib.use('agg')
>>> print (matplotlib.rcParams['backend'])
agg
