python - Matplotlib savefig into different pages of a PDF

I have a lengthy plot, composed o several horizontal subplots organized into a column.

When I call fig.savefig('what.pdf'), the resulting output file shows all the plots crammed onto a single page.

Question: is there a way to tell savefig to save on any number (possibly automatically determined) of pdf pages?

I'd rather avoid multiple files and then os.system('merge ...'), if possible.

See Question&Answers more detail:os
