Ok, you did better on the layout, but we don't need to see all of the graphs.
Rearrange to show the following:
Events,
Flow Rate,
Pressure,
Flow Limitation and
Snores if you can fit it in.
Leave off Pie Chart and Calendar... this allows us to see what's needed.

Fit is important. Measure the circumference of your neck and add a couple inches. It should not restrict your movement but yet keep your head from dropping down when asleep. Also, measure from the bottom of your chin to where your neck starts.
Folk with a short neck need a shorter collar, maybe 2-3", whereas a person with a longer neck can use a collar 3-4" in height.
Check Amazon.
Now take into consideration your bed pillow. Don't use a pillow that's too tall, this will cause your head to tilt forward.
A flatter pillow works better.
If you are able, try to sleep on your side until you find a suitable collar. Although, be aware that chin tucking occurs on your side too.
