SCID (also available as “SCID vs. PC”) has a great feature where based on annotated games (that SCID can also do for you) – you can generate evaluation graphs. They are called Score Graph and are available under tools menu.
Clicking on the place in the graph where the evaluation took a dive on move 14, I can find that White just dropped a piece by leaving the bishop unprotected.
In this case this gives me a better picture of the flow of the game than many verbal annotations that often accompany chess games. SCID does it, and not only for the game that you just played, but for any game stored in your database with engine evaluations!
