Two useful Matplotlib utilities

 1. Latexify_py

latexify is a Python package to compile a fragment of Python source code to a corresponding expression.

2. Pylustrator

Pylustrator offers an interactive interface to find the best way to present your data in a figure for publication. Added formatting an styling can be saved by automatically generated code. To compose multiple figures to panels, pylustrator can compose different subfigures to a single figure.
