It will only retrieve data that exists on the SD Card. Your new profile only shows data that goes back to Aug 4, because that's how far back the data on your SD Card goes.

There is also a setting in OSCAR > Preferences > Import that says "Do not import sessions older than" and a date. Check the date in the box.

Rebooted etc, new profile, still not graphs before August 4th 2021. I can live with it.

There is no detailed data in the DATALOG directory before Aug 4, 2021, so that is why you don't see detailed data after importing from that card.

It showed all of it right back to 28th December 2019 before I updated to 1.3 in October. Although the Resmed wasn't started until 15th January this year. If you went previous to that date the name of machine changed because it had been seeing the SleepStation up till that date. Have no idea why the graphs disappeared before August 4th but when I first wrote the no graphs was before I updated. Using the new profile only showed another couple of months. Still, I at least have all of the AHI numbers on the left for every day I have used this machine.

Thank you kindly for your input.

When OSCAR has to update the database for a machine to a new version, as it did in your case, what it does is to rebuild the database from the backup. If the backup is incomplete, then the rebuilt database will be incomplete.

If the rebuild is interrupted, the new database will be incomplete.

This suggests two possible scenarios:

First, that you interrupted the rebuild for some reason. That's all too easy to do. If that happened, Data > Rebuild CPAP Data > <your machine> might fix the problem.

Second is that your Profiles/<yourprofilename>/<machine>/backups directory does not have backups for everything. That could have happened if you had turned off the option to keep backups in File > Preferences > Import. (That's why the dialog says Turn off at your own peril.)
