This works currently on the agg and ps backends, and requires that you have tex and the other dependencies described at http://matplotlib.org/users/usetex.html properly installed on your system. The first time you run a script you will see a lot of output from tex and associated tools. The next time, the run may be silent, as a lot of the information is cached in ~/.tex.cache """ import numpy as np import matplotlib.pyplot as plt plt.rc('text', usetex=True) plt.rc('font', family='serif') plt.figure(1, figsize=(6, 4)) ax = plt.axes([0.1, 0.1, 0.8, 0.7]) t = np.linspace(0.0, 1.0, 100) s = np.cos(4 * np.pi * t) + 2 plt.plot(t, s) plt.xlabel(r'\textbf{time (s)}') plt.ylabel(r'\textit{voltage (mV)}', fontsize=16) plt.title(r"\TeX\ is Number $\displaystyle\sum_{n=1}^\infty" r"\frac{-e^{i\pi}}{2^n}$!", fontsize=16, color='r') plt.grid(True) plt.savefig('tex_demo') plt.show() Keywords: python, matplotlib, pylab, example, codex (see :ref:`how-to-search-examples`)
