Thanks Thibaut, using eps or other format is a good solution but I was
wondering about the change on file size. Usually, at least in my
experience in linux is that pdf export from matplotlib is very
efficient. In particular, very simple files were exported to small
files. I do not know what (if anything) changed from a few versions back
to the current version in my system (3.2.2) that the minimum file size I
can get now is about 370k.
