is it possible to append figures to Matplotlib's PdfPages?

Question

I want to save 2 figures created at different parts of a script into a PDF using PdfPages, is it possible to append them to the pdf?

Example:

fig = plt.figure()
ax = fig_zoom.add_subplot(111)
ax.plot(range(10), range(10), 'b')

with PdfPages(pdffilepath) as pdf:
    pdf.savefig(fig)

fig1 = plt.figure()
ax = fig_zoom.add_subplot(111)
ax.plot(range(10), range(2, 12), 'r')

with PdfPages(pdffilepath) as pdf:
    pdf.savefig(fig1)

Answer 1

import matplotlib.pyplot as plt 
from matplotlib.backends.backend_pdf import PdfPages

# Use plt to draw whatever you want  
pp = PdfPages('multipage.pdf')
plt.savefig(pp, format='pdf')
pp.savefig()

# Finally, after inserting all the pages, the multipage pdf object has to be closed.  
pp.close()
