Store multiple matplotlib figures as pages in a PDF-file. A PDFFigureContainer is initialized with a Path to a destination.
PDFFigureContainer.add_figure_page() is called to add current figure to the PDF.

# Make a container
container = PDFFigureContainer(Path(output_dir, "container.pdf"))

#
# Make a figure
#

# Add figure to pdf
container.add_figure_page()

Install by pip install matplotlib-pdf

Additional options and uses are:

• The container can buffer many pages by calling container.add_figure_page(commit=False), and them comiting them all to the file using container.update_file() (to avoid constantly updating the file).
• You can specify figure with add_figure_page(figure=fig).

• By running container.set_timestamp() before adding pages to a container, the container will add a time-stamp to each page, allowing reader to see what each page has last been updated (check documentation of method for options to set_timestamp()).
• By running container.set_enumeration() before adding pages to a container, the container will add an enumeration to the pages (ex. 2 / 3) (check documentation of method for options to set_enumeration()).

The example.py-script exemplifies by making three figures and passing them to a PDF-file. It then overwrites the second page with a different figure. The end result is something like:
