是否可以在Matplotlib的PdfPages上附加数字?

问题描述

我想使用PdfPages将在脚本的不同部分创建的2个图形保存到PDF中，是否可以将它们附加到pdf上?

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?

示例:

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)

推荐答案

对不起，这是一个me脚的问题.我们只是不应该使用with语句.

Sorry, that's a lame question. We just shouldn't use the with statement.

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

# create a PdfPages object
pdf = PdfPages(pdffilepath)

# save plot using savefig() method of pdf object
pdf.savefig(fig)

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

pdf.savefig(fig1)

# remember to close the object to ensure writing multiple plots
pdf.close()
