This works currently on the agg and ps backends, and requires that you have tex and the other dependencies described in the :doc:`/tutorials/text/usetex` tutorial 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. Notice how the label for the y axis is provided using unicode! .. image:: /gallery/text_labels_and_annotations/images/sphx_glr_tex_demo_001.png :class: sphx-glr-single-img .. code-block:: python import numpy as np import matplotlib matplotlib.rcParams['text.usetex'] = True import matplotlib.pyplot as plt t = np.linspace(0.0, 1.0, 100) s = np.cos(4 * np.pi * t) + 2 fig, ax = plt.subplots(figsize=(6, 4), tight_layout=True) ax.plot(t, s) ax.set_xlabel(r'\textbf{time (s)}') ax.set_ylabel('\\textit{Velocity (\N{DEGREE SIGN}/sec)}', fontsize=16) ax.set_title(r'\TeX\ is Number $\displaystyle\sum_{n=1}^\infty' r'\frac{-e^{i\pi}}{2^n}$!', fontsize=16, color='r') plt.show() .. _sphx_glr_download_gallery_text_labels_and_annotations_tex_demo.py: .. only :: html .. container:: sphx-glr-footer :class: sphx-glr-footer-example .. container:: sphx-glr-download :download:`Download Python source code: tex_demo.py ` .. container:: sphx-glr-download :download:`Download Jupyter notebook: tex_demo.ipynb ` .. only:: html .. rst-class:: sphx-glr-signature Keywords: matplotlib code example, codex, python plot, pyplot `Gallery generated by Sphinx-Gallery `_
