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.
