@mathmagic, Your masterpiece works as a dream for me:) It is perfect and dynamically show how things go together. But it is really a little confused for me to understand it.

Can you kindly give a more static version and just show what allowed in the question.png? (because i do not know how to control staff not changes lively:))

Or can you give a little explaination on how does that work? (i do not know why the chart changes along time, how to stop that? )

thanks a lot~
