Heart-Rate Zone Charting/Graphing

We have had this rather informal 'Enhanced Heart-Rate Zone' logging for a long time, but no tutorial and no way to get some numbers on % time spent training in a zone, etc. 

Marmadaddy took this one on a few months ago and after debugging it this month, we think it's ready for prime-time.  He did a lot of work-and it turned out very, very nice.

So for all of you zone people, the link below is the tutorial (very easy).
