Weird pressure graphs in SleepyHead

I went a few months without looking at my CPAP data. During that time, I got a new computer and installed SleepyHead 0.9.6 on it. This is a different version than I used to use on my old computer. I now see some funky fluctuations in the pressure graphs. They used to always show flat lines. Is there a problem with my CPAP machine? Or is this due to a SleepyHead change?

I have a Resmed S9 Elite. Ramp and EPR are turned off.

It's related to SleepyHead I am sure.
Which new version is this?

It's v0.9.6 (testing) for Windows. The build date is Jun 23 2014 16:34:18.

I don't know if turning off pixmap caching will fix the issue but worth a try. Go to Preferences then the Appearance tab and remove check mark by "use pixmap caching".

If not don't worry about it. It's a SleepyHead bug of some sort I am sure. The Testing versions are just what they say they are...testing versions and buggy.

Which version did you use in the past? I might have 0.9.3 somewhere you could use until the next SleepyHead version gets released. I know Mark is working on things but time frame is unknown as to when the next version will be released.
Or you could use ResScan if you wish just to reassure yourself that it's SH (which I am sure it is) who is having the problem.
If the whacko looking pressure line is all that is off I wouldn't worry about it.

Thanks for the tip, Pugsy. I played with pixmap caching and didn't see any difference in the shape of the graph. It looks like that setting only affects the font used for the graph labels.

I don't remember what version I used in the past. If you have a stable version I can use, I'd really appreciate it. SleepyHead is a lot better than ResScan.

You have a Resmed machine so why don't you use ResScan? I would never use SleepyHead to check my treatment. See here my recent full year Stats results:


Nightly graphs and stats:









Let me get some from when I used an S9 Elite from 3 years ago.

I tried ResScan for a while last year. The thing I remember most is that It was very slow. SleepyHead is a lot more responsive, plus it presents the data in a format I like.

Pugsy, I installed the version I got from you. Thanks again for that. The interface looks just the like the verison I used to use.



Since my S9 hasn't turned into a super powerful vacuum cleaner (which apparently suffered an explosion at 1:45 am), I'm concluding that there's still a data problem somewhere.

I used to use Windows 7, now I'm on 8.1. So, the problem appears to be with my Windows version, my SD card, or my CPAP machine. I'll reformat the SD card and reboot the S9. Then I'll look at the data again in a couple of days.
