mplunitx is a Python package heavily inspired by the LaTeX package siunitx intended to be used complementary with matplotlib.
matplotlib supports some LaTeX in its text rendering,
but not the use of siunitx. Using siunitx is possible with
text.usetex=True in the matplotlib rc settings, but this needs a
local installation of LaTeX and keeping the fonts consistent is not trivial.
mplunitx aims to provide a similar functionality to siunitx by
imitating the \num, \unit and \qty commands with python functions,
which return strings with LaTeX code that matplotlib understands.
For the labels of the axes, the mplunitx package additionally provides
a function for typesetting the variable name and unit with either "/" in
between or "[]" around the unit.
Install with
pip install mplunitx
