Ask for some questions about chart output data!

#1

Dear Anybody:

I am a college student and I am learning the Anybody software. There were three problems encountered during the learning process.

1.Does the first list of lumbar muscles represent a list of lumbar muscle activity? If not, what does it mean?

2.The code behind the second color curve can be used to find out which muscle is the specific one?

3.I want to know the names of the muscles of the curves that are obviously changing in the third position. Where can I find them?

Thank you very much!
Looking forward to your reply!
