How do you determine which backend is being used by matplotlib?

Question

Either interactively, such as from within an Ipython session, or from within a script, how can you determine which backend is being used by matplotlib?

Answer 1

Use the get_backend() function to obtain a string denoting which backend is in use:

>>> import matplotlib >>> matplotlib.get_backend() 'TkAgg' 

Answer 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
