在不使用子图的情况下将多个图形保存在一个pdf页面中 [英] Save multiple figures in one pdf page without using subplots

问题描述

我有很多数字，我想以pdf格式将它们放在同一页上. 目前，我正在使用PDF后端，但每个数字只能将它们写在一页上.

I have a lot of figures and i want to get them on the same page in a pdf. Currently i am using the PDF backend, but it only writes them on one page per figure.

要获得一页上的数字列表，需要进行哪些更改?

What changes are needed to get a list of figures on one page?

由于代码的多种原因，我不想使用子图. 因此，假设无法更改绘图部分. 我只想更改将数字保存到pdf的部分:

I don't want to use subplots because of several reasons of the code. So let's say it is not possible to change the plotting part. I only want to change the part where i save the figures to the pdf:

for i in range(number_of_figures):
    fig = figures[i]
    pp.savefig(fig)

pp.close()

有人有主意吗?

推荐答案

我过去也遇到过同样的问题，但也无法解决.

I have come to the same issue in the past and wasn't able to solve too.

我的解决方法是将图形保存到磁盘，然后使用其他模块将其加入.

My workaround was to save the figures to disk, then use a different module to join them.

签出以下代码:

from PyPDF2 import PdfFileMerger

files = ['f1.pdf', 'f2.pdf']  # put the full path for the file you wanna join

merger = PdfFileMerger()
for pdf in files:
    merger.append(open(pdf, 'rb'))
joined_pdf_path = 'joined_pdf_file.pdf'
with open(joined_pdf_path, 'wb') as fout:
    merger.write(fout)
