Hi Daniel,
As Bala alluded - there's a difference between display dpi and
the file saving dpi. Your change to rcParams only affected the
displayed resolution, not the resolution of saved files.
Quoting from .matplotlibrc
# the default savefig params can be different from the display params
# Eg, you may want a higher resolution, or to make the figure
# background white
#savefig.dpi : 100 # figure dots per inch
So try playing around with that parameter (which is what you're
doing if you call plt.savefig('name', dpi=300)
best,
