Hi Benjamen,

As is also reported in Bug 1898890, I install MA V1.9.6 manually by
overwriting the folder HEPTools/madanalysis5/madanalysis5. I still see the
same problem concerning the PDF outputs.

For testing the matplotlib, which python code should I use to generate the
plots?

Best regards,
Jie
