# How to change the names of the registers displayed with circuit_drawer (output='mpl')

I am trying to change the appearance of the circuit_drawer in output='mpl' mode. The registers of the Quantum Circuit are named like ($$q0_0$$, $$q0_1$$, $$q1_0$$, $$q2_0$$, $$q2_1$$,..) but I'd like to name them myself. I can't find a style function or option which is able to do that... any ideas?

To be clear what I would like to change:

f_in = QuantumRegister(n, name='f_in')
