Matplotlib tips
===============


True TeX labels
---------------

The plotting utilities of matplotlib can use the power of a TeX system if
one is installed. We just have to tell matplotlib that it should generate
the labels with the help of TeX. We then can use anything that is a valid
TeX expression we would otherwise write between the dollar signs in a TeX
file. The following code presents a small example showing TeX labels in action.

NOTE: you may have issues with the following usetex-options in case that latex
is bad configured on MacOS or Windows.

.. literalinclude:: TutCodes/tex_labels.py
   :language: python

.. plot:: TutCodes/tex_labels.py

Note that we have to use so called raw strings, i.e. strings with the
character ``r`` as a prefix. Additionally we use the dollar signs inside
the strings for delimiting formulas as usual.
