There are two user's guides available, which between them cover most of your questions. They are at the beginning of this thread: http://www.apneaboard.com/forums/Thread-...Discussion
and a wiki on Sourceforge: http://sleepyhead.sourceforge.net/wiki/i...sers_Guide
As you know, SleepyHead is being developed by JediMark in his own time as a free service. For this reason, there are a number of versions floating around and the documentation isn't always up to date with the latest version. There may also be differences in the way things appear on a Mac, but I can't really comment as I use a PC.
In relation to your last couple of questions:
The yellow and green items jctampa is referring to are the Cheyne Stokes Respiration and RERA in the legend of the screenshot he posted. See here:
The yellow items you're referring to are little pop-ups which JediMark has provided to assist in understanding the output. The legend will be different for different machines as they report different data. From what I've seen the Philips machines tend to report more than the ResMeds, but each model is different and will have its own legend.
The grey area in the event flags bar indicates how far zoomed in you are. If you're fully zoomed out (showing the whole night's data) then nothing is grey. You can click and drag in that bar to zoom in on a particular event - the non-grey area represents the time span shown in the detailed graphs and the grey area is excluded. Or, to put it another way: The event flags is the main "control" graph, it represents a time-line of the event data available for a day. This graph does not zoom, instead it highlights the selected area, allowing for quicker control/zooming around graphs.
Hope this helps.
Thanks Paul from Perth for your comments, and clearing up the identity of the yellow and green items. I would never have guessed.
I still don't quite understand the purpose (ie use) of the grey v non-grey
areas on the Events Flags (Daily) graphs, nor the varying times scales of these graphs - I have never been able to set the time interval for my complete sleep history eg 12hr or possibly 24 hr time period.
I was a little non-plussed when the instructions for operating Mac version of SH were not possible on my Mac (eg different pulldown menu functions, and different F key functions). I have no idea why on my Mac they are different, since it is as bought with some OS upgrades.
I have used a PC for many years, but gave up when they deserted XPpro, for these weird W7, W8, W8.1, which I tried - I thought they were trying to be fake Mac. Since the Upgrade (not Install) from XP to W7 destroyed many of my files, I decided that it would be an excellent time to switch to Apple.
I suppose I don't really comprehend the zoom function that you mention. One ting I notice about the green cursor - some of my graphs are extremely spiky, but I can never get the green cursor to display the value of a spike - of course I can read it off the Ordinate axis.
I recognize Jedimark's work, and have made small donations to the Apnea Board, since it does not appear possible to make a donation at Source Forge.
I don't quite understand: "The event flags is the main "control" graph, it represents a time-line of the event data available for a day. This graph does not zoom, instead it highlights the selected area, allowing for quicker control/zooming around graphs." Is there a reference that explains how to work with these data, eg show the whole interval as displayed on the Summary/Session Times graph?
In response to a previous request, I tried to send a copy of the Daily By Pressure Graph. I copied from the screen, but could not copy it into a comment, but had to attach it as a file. Apparently the file type I chose, also a Source Forge file type, was not compatible with the Post software, and was dropped from the post.
But thanks for your assistance. (I notice that my current Event Breakdown Pie is all Dark Blue - pure Hypopnea! an uneventful night, apparently.)
