Multiple fontsize in same label Matplotlib

Question

I\'m trying to do something relatively simple:

I want to be able to increase a font of one letter(say a LaTeX variable, say to 30) and keep the other letters in the

Answer 1

One solution is to use text() and make multiple calls, carefully selecting where each letter goes:

import pylab as plt
a=[0,1]
b=[0,1]
plt.plot(a,b,'g',linewidth=3.5, label = 'a')
plt.rc('text', usetex=True)
plt.legend(labelspacing = 1.0,loc=1,prop={'size':40})

plt.text(0.45,-0.08,'a',fontsize=50)
plt.text(0.53,-0.08, 'N',fontsize = 20)

This isn't ideal. Another option is to go through LaTeX. See other answer I'm about to post.
