Thanks for joining the forums, and reaching out, any issues or requests should occur in the technical support forums. https://www.brewersfriend.com/forum/#brewers-friend-technical-support.4 When I looked at your most recent brew session, none of the log entries you made are ones that generate a fermentation chart. In order to manually add them to the chart, you'll need to check this box.
I had the same confusion when I first started using Brewers Friend. Since I don't have any devices feeding fermentation data to BF, I track temperature or gravity readings by using the "Sample" event type.
