This is more a bug then an idea. But someone who made this zoom function must have clearly saw that it doesn't work at all (just can't miss that Y scaling is not implemented), so they know, but don't care…
It takes some determination and a lot of patience to get through via email, but Garmin has fixed some of the bugs I have reported. Make sure you get a case number so that the engineers do investigate.
Garmin only monitors a small number of the forums so writing here is no guarantee that Garmin will act. If everyone who has +1ed on this post emails Garmin they might do something though.
they should use a logaritmic scale in the Y, so the closer to 0 (faster) the more zoomed would it be) Indeed 15 sec/km diffeernce are a lot when you run ar 4':00"/km, but are nothing when you hike at 25':00"/km
+9357 This is by far the biggest flaw in Garmin Connect - and has been for ever!
Should be easy to fix: Make the user enter a threshold value that should be the lowest pace on the y-axis, and scale between this value and the max-pace value. Min-pace value can be stored in user profile.
Analyze data and get 95% of data points in Y-Axis. We need to ignore those fallouts when you've stopped at a traffic light and restart. Or, just have Garmin assume the same pace from before the stop for the first 15 seconds until it re-establishes speeds. I can't believe the Garmin decisionmakers think these graphs are useful. Maybe all of them run and never stop mid-run! Please, after this many years, add the data field to let us enter a high/low Y-axis and let HighCharts re-calculate the graph. I'm about to send these pages to my own HighCharts engineers and ask them for help!

Not a bad idea, but it doesn't cover the case when you run intervals and you have significant periods of standing or jogging rest time.
I actually like how both Strava and the Garmin Connect mobile app (not website) handle this -- they just have an arbitrary minimum pace on the y-axis like 11:00/k. The Garmin Connect website kinda does the same thing, except their arbitrary minimum is arguably chosen more poorly (40:00/k).

Runalyze does this and I agree it would be the best solution, but I don't think it would make sense to non-technical users.
