如何从IPython Notebook将图形导出到文件 [英] How to export figures to files from IPython Notebook

问题描述

我将IPython Notebook与--pylab inline选项一起使用，因为我不希望将图显示在其他窗口中.现在，我想将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

，但是这似乎在串联模式下不起作用.

but this does not seem to work in inline mode.

当然，我可以简单地保存从浏览器中生成的PNG，但是我想用一行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

尝试此操作(请注意，文件已保存到默认笔记本文件夹中):

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()调用应与绘图命令位于相同的笔记本单元格中.

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