Time histogram plotter

Plot time evolution of electron energy spectrum with the density profile.

To run, python histogram_evol.py. To generate the corresponding jupyter notebook, we use jupytext.

To generate a jupyter notebook from a Python script, do:

jupytext histogram_evol.py --to ipynb

One then has to delete the original Python script, which will be re-generated by Jupyter.

For LaTeX font rendering of matplotlib figures, under Ubuntu 20.04:
