[IPython-dev] matplotlibrc seems to be ignored from IPython notebook

[Min RK]

Did you not receive my reply yesterday?  Yes, it is only the inline backend that sets a few defaults.

Resending:

It is not ignored, but IPython sets a few of its own defaults with the InlineBackend.rc config . One of these is savefig.dpi.  You can prevent this by simply clearing the inline backend rc with:

c.InlineBackend.rc = {}

in your config file.
