I added support to the pdf backend for multipage pdf files. The current API (which I'm not entirely happy with) is that you create a PdfFile object, plot your figures, saving each one to the PdfFile object, and then close the object. The part I'm unhappy about is that because PdfFile is a file-like object - it has a write method - you can accidentally save your figure as a png into it and get a broken pdf file. You have to specify format='pdf' to savefig to avoid this.
Here's an example: from matplotlib.backends.backend_pdf import PdfFile pdf = PdfFile('multipage_pdf.pdf') figure(...) # build your figure savefig(pdf, format='pdf') # repeat for all your figures pdf.close() -- Jouni K.
