# Energy level diagram - software

Which easy-to-handle software would you recommend me for creating energy level diagrams? What do you use and what is your experience? I'm recently working on my bachelor thesis and I would like to add some pictures to ilustrate Hund rules, Zeeman splitting, crystal field splitting and so on with option to customize them on my own. Cheers!

• I'm not sure this is within the scope of this site. The software you describe doesn't appear to be as much computational as graphical in nature, and you appear to be asking for recommendations rather than something more how-to with a specific library or package. As a general advice you might investigate how others did the diagrams in the literature you are most familiar with. – hardmath Jul 16 '13 at 19:49
• I use matplotlib for everything. – Ondřej Čertík Jul 18 '13 at 21:51

Depending on what you want to show, the matplotlib library for python may also be a good solution. In particular, I would like to direct you to the hlines function and this article on annotating your plots.
