sleepyhead wave forms - BillMar - 03-08-2015
I have been using SH for a few days and have about three weeks of accumulated data for the SD card.
Today when I added the March 7 data I noticed that the wave forms are different than the prior days. As you can see from the attached image the time starts on the "x" axis from about 17:00 and "scrunches" the data to the right. In prior days the data began about 23:00 which was about when I went to sleep and end at about 8:00 and the data filled the entire "X" axis period; the entire graph data filled the entire area. Now it is as a say scrunched into the right hand side. I would like to correct this for the 7th and avoid it happening in the future.
I have changed nothing in preferences etc. And wonder if it could have something to do with the switch to DST which went into effect last night in the USA. I am using a Phillips System One.
Any thoughts to fix this and avoid the problem going forward would be appreciated.

Don't waste time on this "problem"
I am the problem! The waveforms are skewed to the right because I ran the machine about 16:00 hours for about 20 minutes to dry out the tubing which I had washed--according to the instructions of the supplier and of course that started a session.
I then turned off the machine until went to bed and started the normal therapy. Hence the "crazy" waveform.
Sorry if anyone has taken time on this before I have posted this correction. Rather obvious now

ha ha. a lot of what we see is because of what we do. it's ok, I guessed there might be a short session before 17:30 due to the event bar.
what's really funny is I ran mine much the same, having cleaned my tubing, I blew mine dry as well.... I expected to see the same thing, but didn't get that pleasure.
only thing I can think of is on my sleepyhead preferences, there is a setting to ignore any session less than x minutes, mine set on 5 minutes. I must not have blown it for over 5 minutes.
