将 matplotlib 图形另存为 .pdf_tex

Question

In Inkscape, there is the possibility of saving pdf files along with generating pdf_tex files for automatic formatting into a Latex file. This can be specified by checking a box after clicking on save and specifying the extension as .pdf .

I'm interested in directly saving, from my python script, matplotlib figures in that specific format.

Does this possibility exist or can it be done with some tricks?

Answer 1

An option is to export a pdf from matplotlib and then use inkscape programmatically, ie through the command line interface to let it create the desired format.

import matplotlib.pyplot as plt

plt.bar(x=[1,2], height=[3,4], label="Bar")
plt.legend()
plt.xlabel("Label")
plt.title("title")

def savepdf_tex(fig, name, **kwargs):
    import subprocess, os
    fig.savefig("temp.pdf", format="pdf", **kwargs)
    incmd = ["inkscape", "temp.pdf", "--export-pdf={}.pdf".format(name),
             "--export-latex"] #"--export-ignore-filters",
    subprocess.check_output(incmd)
    os.remove("temp.pdf")


savepdf_tex(plt.gcf(), "latest")

plt.show()

Also note that matplotlib can save in the pgf format. It's definitely worth trying as an alternative to the above. See this example , and append plt.savefig("filename.pgf") to it. In the latex code use \input{filename.pgf} .

Answer 2

As matplotlib backend

I created a matplotlib backend a few years ago specifically to support this feature. However, it is only compatible with older matplotlib versions and must be updated (I would appreciate any contributions).

Directly from your script

@ImportanceOfBeingErnest has already mentioned this. However, if that solution fails, try it with --export-filename or -o instead of --export-pdf .
