Is it possible to look at the charts and tell when you are awake and when you are asleep, and what kind of sleep you are in? If so, which charts are best to look at for this purpose?

Short answer: No. You need a lot more data than what can be garnered from breathing and flow patterns to determine sleep and which level. With that said; Your breathing patterns are more uniform when you sleep as opposed to while you're awake. That's why you tend to ignore any reported CA's when you are going to sleep and when you are waking up.

I know; Bummer!

with a little practice, you can get a pretty good idea of when you're awake and when you're asleep by zooming in on the flow chart.

sleep breathing and awake breathing typically look rather different, though it's not 100%, both resmed and fischer & paykel use this in their machines, resmed in the airsense 10 machines to start ramping up pressure once your breathing indicates you're asleep, and F&P to reduce pressure when the machine thinks you're asleep.

here's a very brief example: http://www.osahelp.com/#6

Thanks, for responses.
The link is what I was looking for. It explains it in simple terms even I can understand.
