I wrote the (admittedly primitive) attached savefigppt() function to save multiple PyPlot images to a Powerpoint-compatible .pptx file (works on both Windows and Linux). When adding an image to a file, if the file already exists then the image will be added to a new page appended at the end. The Powerpoint file can then be converted to other formats, presumably including PDF. Note that you must have installed the Julia packages PyCall and PyPlot, and the Python package python-pptx (see https://python-pptx.readthedocs.org/en/latest).
