Hello Lorenzo, maybe you don't really use Tex to build the labels and mathtext does not support any Tex-functionality. if you use: ------------------------------------ from matplotlib import rc rc('text', usetex=True) import pylab as p ------------------------------------ it should work. Alternatively you could modify your matplotlibrc directly.
