Not sure if this is a bug or user error, but my altitude charts go to zero for the period when I stop riding, even for a minute, which then makes it hard to do the kind of analysis I want. Data is coming in via a Coros watch.
Thanks!
Auto-pause?
Can you please post a link to one of these. Tx.
I’ve noticed something similar with my Coros Pace 2 generated files. The elevation in the raw data is always zero for the first few seconds. David - have a look at any of my files for the first half of this year (I’ve switched back to Garmin now).
Not only elevation, HR also has 0 on the first second of the recording. That’s a Coros bug off course, but maybe David can ignore 0’s? HR = 0 at the start of a recording isn’t going to be something that happens a lot in real life 
I always have to crop the first second or otherwise the vertical auto-scaling for those charts have little meaning.
Maybe the OP’s problem happens when he stops/restarts the recording and the start again has a 0??

Thanks folks - AutoPause was the culprit, and moving the “Show Pauses” slider in the “Options” menu while viewing an activity was the fix.
