问题描述

我使用带有 --pylab inline 选项的 IPython Notebook,因为我不希望绘图显示在不同的窗口中.现在我想将我在笔记本中看到的图保存为 PDF 或 PNG 文件.

I use the IPython Notebook with the --pylab inline option, since I don't want plots to show up in a different window. Now I'd like to save the plots I see in the notebook to PDF or PNG files.

一些代码示例使用

import matplotlib as plt

plt.savefig("figure.png") # save as png

但这似乎不适用于内联模式.

but this does not seem to work in inline mode.

当然,我可以简单地保存从浏览器生成的 PNG,但我想用一行 Python 来做到这一点.我也对 PDF 导出感兴趣.

Of course I could simply save the PNG that is generated out of the browser, but I'd like to do this with a line of Python. I am also interested in PDF export.

推荐答案

试试这个(注意文件被保存到默认的笔记本文件夹):

try this (note that the files get saved to the default notebook folder):

plot(range(80))
xlabel('foo')
ylabel('bar')
legend(['myline'])
axis([0, 80, 0, 120])
savefig('sample.pdf')

如果你想要 png 只需将其更改为 'sample.png'.

if you want png just change it to 'sample.png'.

请注意,savefig() 调用应该与绘图命令位于相同的笔记本单元中.

Note that the savefig() call should be in the same notebook cell as the plotting commands.
