That's standard behaviour IIRC. If you're not downloading archive data
correctly (which you're clearly not, as per your previous post) then
the barograph has got no permanent store of pressure data on which to
call to recreate the trace whenever it reopens the program. It does
separately maintain a temporary store of recent pressure data for as
long as the program is open, but that's lost when the program is
closed. Normal barograph service should be resumed if you can get the
archive downloads working and configure automatic archive downloads
appropriately.

Right, I've cleared all the logs and set up a new station, and this
has been running for about an hour and a half, but no data is being
recorded at all. I don't know if this narrows down the problem or
not.
