When I view an activity on Garmin Connect, the elevation profile is shown over time. On expanding that view, it's possible to see elevation plotted against distance too, but this doesn't seem to be possible on the main screen. I'd like 'over distance' to be the default setting for the main page - am I able to change this? If not, please would it be possible to add this feature?
It is probably correct that the default can't be changed.
But it is not correct that you have to expand the view to be able to see elevation over distance. There is a button for that in the main view, just below the lower right corner of the map.
It's even more of a screw-up in the phone app version of Connect, where it's absolutely impossible to change to horizontal axis for the profile graph to distance rather than time.
