Test tests/tests_complexity.py::test_complexity_vs_Python failed. Very unlikely this was due to my fix.

Hi @tiagofrepereira2012, thanks for your PR. Unfortunately, we made the design decision to not return the figure as it creates double figures depending on the backend and config.

You can still retrieve the fig by doing for instance:

nk.ppg_plot(...)
fig = plt.gcf()
fig.set_size_inches(10, 12, forward=True)
fig.savefig("myfig.png")

Hope that helps :)

Sure. I'm closing it

Thanks
