I've already tried the instructions on the qiskit page and even from this other question What is the location of the Qiskit config file? but it doesn´t work, the circuit keeps looking as text based, even i restarted jupyter notebook, and nothing. The settings.conf file wasn't in the directory so i created one but still no results.

    I’m voting to close this question because it's a question about a specific python package/functionality and has nothing to do with QC or quantum mechanics per se – glS Mar 10 '21 at 11:40
  • Does it have to be about quantum mechanics? The questiin is about qiskit and is more likely to be answered here than elsewhere. – user1271772 No more free time Mar 10 '21 at 15:14
  • This is not a difficult problem, I think. Try circ.draw('mpl') and then `plt.show()'. But you really need to describe the situation specifically because it is not clear what really happens. – Yitian Wang Mar 11 '21 at 06:49
  • the problem is that i want qiskit to plot on mpl by default the circuits and so, but following the instructions of it makes no changes, like if qiskit wasn't able to recognize the settings file or something like that – Antonio Vallejo Mar 12 '21 at 23:59

To check that the content of the setting.conf file is properly set you can run the following

from qiskit import user_config
user_config.get_config()

{'circuit_drawer': 'mpl'}

If this is not your output, then your setting.conf is out of format or in the wrong location. You can fix the location by setting the env variable QISKIT_SETTINGS. It is possible to do that in a Jupyter notebook with this magic:

%env QISKIT_SETTINGS <path to your setting.conf>
