Living in a relative flat country, I want the altitude graph to use the full screen.
There are even different levels for different watches it seems.
See my samples below from FR305 and 910XT:
Most line are too flat, and I can't zoom close enough. And of course I want to be able to adjust the lower limit. I.e. never show below 140 bpm in HR. But the -200 meters in altitude is just crazy when it goes from 34m to 65 meters or thereabout. Run cadence should also allow me to zoom to the 80-92 range. Everything outside that range is not important for my analysis.
