LevelScheme is a scientific figure preparation system for Mathematica. LevelScheme provides a general infrastructure for the preparation of publication-quality figures, combining technical drawings or diagrams, mathematical plots, data plots, and annotations. It features extensive support for multipanel and inset plotting, customizable tick mark generation, diagram construction, and labeling.
LevelScheme originated as a tool for drawing level schemes, or level energy diagrams, as used in nuclear, atomic, molecular, and hadronic physics. LevelScheme includes a full suite of drawing tools for the construction of such diagrams. LevelScheme automates many of the tedious aspects of preparing a level scheme, such as positioning transition arrows between levels or placing text labels alongside the objects
they label. LevelScheme allows extensive manual fine tuning of the drawing appearance, text formatting, and object positioning. It also includes specialized features for creating several common types of level schemes encountered in nuclear physics. The full power of Mathematica’s programming language may be used in constructing the figure contents, so, for instance, level energies and transition properties shown in the diagram can be directly computed from models or input from data files.

LevelScheme features

• multi-panel and inset figures,
• convenient tools for labeling and annotating figures, and
• customizable tick marks,

as well as a variety of drawing elements (lines, arrows, boxes, circles, etc.) you may use to create diagrams.  The figures you create can incorporate any kind of plot or graphics produced by Mathematica.  You can therefore easily combine

• mathematical plots,
• data plots, and
• technical drawings or diagrams
