[FIXED] Python saving multiple figures into one PDF file

Issue

In python (for one figure created in a GUI) I was able to save the figure under .jpg and also .pdf by either using:

plt.savefig(filename1 +  '.pdf')

or

plt.savefig(filename1 +  '.jpg')

Using one file I would like to save multiple figures in either .pdf or .jpg (just like its done in math lab). Can anybody please help with this?

Solution

Use PdfPages to solve your problem. Pass your figure object to the savefig method.

For example, if you have a whole pile of figure objects open and you want to save them into a multi-page PDF, you might do:

import matplotlib.backends.backend_pdf
pdf = matplotlib.backends.backend_pdf.PdfPages("output.pdf")
for fig in xrange(1, figure().number): ## will open an empty extra figure :(
    pdf.savefig( fig )
pdf.close()
