I would like to see two additions to the altitude, speed, grade, hr graph.
Currently there are two x axis options, time from start and distance. I suggest an option of clock time. Where was I at 8 AM. Or, when I was here, what time was it? Yes, these things can be calculated. I'd rather not.
The y-axis for altitude is always from sea level. I'd like to see an option to switch to relative altitude. Zero could be the start of the ride (I think I'd prefer that). Or zero could be the minimum altitude of the ride. At any rate, it would make much more clear the altitude changes.Ideally, the "tooltip" that shows altitude, HR, etc. would reflect the relative altitude as well.
