使用patchworklib到output多页PDF

Question

I am attempting to use the Python package patchworklib to create complex plot layouts and then output them to a multi-page PDF. 我已经成功地完成了 output 单页 PDF 但不知道如何创建多页 PDF。 以下是我迄今为止尝试过的一些示例。

import matplotlib.pyplot as plt
from matplotlib.backends.backend_pdf import PdfPages
import patchworklib as pw
import seaborn as sns
penguins = sns.load_dataset("penguins")

sns.set_theme()
pw.overwrite_axisgrid() 
g1 = sns.relplot(data=penguins, x='bill_length_mm', y='bill_depth_mm', col='species')
g1 = pw.load_seaborngrid(g1)
g2 = sns.relplot(data=penguins, x='bill_length_mm', y='bill_depth_mm', col='species')
g2 = pw.load_seaborngrid(g2)

# Produces correct plot, but no idea how to leverage this for multi-page PDF
(g1/g2).savefig("test.pdf")

# Valid multi-page PDF produced, plots are messed up
with PdfPages('test.pdf') as pdf:
     pdf.savefig((g1/g2).savefig())
     plt.close()

     pdf.savefig((g1/g2).savefig())
     plt.close()

# Creates corrupted PDF (won't open)
with PdfPages('test.pdf') as pdf:
     (g1/g2).savefig(pdf._file)
     plt.close()

     (g1/g2).savefig(pdf._file)
     plt.close()
