Zooming progression chart

How do I zoom out or change the start date of the progression chart? I cannot get it to start earlier than September, but I have loaded data for all of 2017.

Looked into this more. Seems that the issue is that when I set a custom data range for Strava import to be all of 2017, I only get from September forward to the current date. Is there anyway to load earlier data, or is this a limitation of the system?

Please read our FAQ on how to sync your Strava activities.

Thanks, I missed the “select all” step
