Mine is the same - reboot, new version and the graphs look good.

- per minute data is held for two days in the RAM database and then discarded
- if the per-minute archiving option is chosen, minute based mapped sensor data and related derived data is stored in the database
- otherwise the storage/archiving is hour based (in case of minute based option activated: both - minute and hour).

You can check this yourself using e.g. sqlitebrowser on a Windows PC and reading a backup of your database (the backup is a 1:1 copy of your database at the point in time of the backup).
You can also use sqlitebrowser on a Linux computer

It was a glitch on the chart display part, storage of data was not impacted. Most recent releases have it fixed. Sorry for the inconvenience.
