Re: [Matplotlib-users] Shadows are really large in exported PNG file
A quick follow-up: if I export to a jpg file, I get the same huge shadow. If I
export to a PDF file, the shadow looks much more like it does on the screen.

[Matplotlib-users] matplotlibrc seems to be ignored from IPython notebook
I want to increase the default setting of saved matplotlib graphs, so I
created a file ~/.matplotlib/matplotlibrc containing the line
savefigdpi : 300
I then created a test notebook containing a single cell with the contents
import numpy as np
import matplotlib.pyplot as plt
x = np.array([1,2,3])
y = np.array([4,5,6])
plt.plot(x,y)
plt.savefig('d0.png')
plt.savefig('d300.png',dpi=300)
When I run this within the notebook, the two png files are created fine,
but have different sizes. When I run the same code from the command line
(after saving the same commands to a script file testplot.py), using
ipython testplot.py
the two graphs have the same size, as desired. Does matplotlib ignore the
contents of ~/.matplotlib/matplotlibrc when called from an Ipython
notebook?
By the way, this is using matplotlib 1.2.0 and Ipython 0.13.2, if it makes
any difference.
Thanks for any help.
