Track Profile - Multiple Data Overlays

[KenF]

Garmin finally got around to a software upgrade (2.30) for the Foretrex 401 to make HR data downloadable. (Yet they have not updated this info on the relevant web page. https://buy.garmin.com/shop/store/downloadsUpdates.jsp?product=010-00777-00&cID=144&pID=30026)

TF handles the new download capability just fine.

So what I'd like to see is more graphical information available in the "Profile" box.   
A simple option to  provide multiple simultaneous choices (overlays) of the presently existing options in the "Y-axis" drop-down menu would do it.

I'd still like to see this. Toggling between different Y axis displays isn't very useful for comparing different data types.
It would be nice to be able to see, for example, heart rate and elevation graphs overlaid on each other.
