Is this example from the docs what you want?

Or even just plot(x^2,(x,0,2), fontsize=20)

Note that these answers are for sagecommands. If you are looking for how to deal with matplotlib plots, it might be better to post to the matplotlib help list. Or personally, I usually just look at the matplotlib gallery ( and find something close to what I want.

yticks(fontsize=SIZE) should work:

import pylab
import matplotlib
#pylab.rc('text', fontsize=18) #This is a 'bad' but effective way to change the default font size
pylab.plot(xdata, ydata, '--')
pylab.savefig('transspeclin.pdf', format='pdf')
