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.
I haven't tried myself, but in the matplolib faq there are some instruction to save plots in pdf in several pages.
I suspect that there is a more elegant way to do this, but one option is to use tempfiles or StringIO to avoid making traditional files on the system and then you can piece those together.
