问题
I am using ob-ipython on org-mode, which positions the images from matpllotlib automatically.
However, the images it output is quite small.
search through the source code and did not find keywords of 'pic' or 'img'.

How could double the size of images?
回答1:
This is a matplotlib setting.
#+BEGIN_SRC ipython :session :results raw drawer
%matplotlib inline
import matplotlib.pyplot as plt
import numpy as np
plt.rcParams['figure.figsize'] = [12, 8]
#+END_SRC
#+BEGIN_SRC ipython :session :exports both :results raw drawer
plt.hist(np.random.randn(20000), bins=200)
#+END_SRC
For me the default seemed to be [6,4]. Apparently it's measured in inches; there's also a DPI setting. It guesses my DPI wrong (default is 72, my actual DPI is 87 according to xdpyinfo and a ruler), and also the image size isn't quite right even assuming 72 DPI, but it's not super far off.
BTW, this is the first time I've actually got ob-ipython working, seems pretty nice.
