I can generate the .pgf without having to setup the backend which I think
is the expected behavior. According to the docs:
"Figures can also be directly compiled and saved to PDF with
plt.savefig('figure.pdf') by either switching to the backend..."
So it seems its only needed to save the PDFs... You may try directly in
Python to see what hapens.About the settings, I do copy-paste and change them as I need for each plot.
