Gray bars in sleepyhead overview USAGE graph
#1
Question 
When sleepyhead displays its overview tab, the usage graph color codes the bars. Most of them are blue, and those for days of less than 4 hours are red. That is useful, but then a few days display a gray bar. What is that supposed to mean? Over several weeks of usage, bars for some days have change from gray to blue as I have imported an SD card from my machine every day. One day three months back has remained gray to this very day. The most recent gray day was just 2 days ago.
What does the gray color indicate?
If anyone knows, I'd really appreciate finding out.

G'day Qualtech, welcome to Apnea Board.

I believe the grey nights are those when you don't have any detailed data, just the summary stuff. Did you leave the SD card out of the machine? Or wait more than a week between downloads? That's what causes grey nights for me.

If you check your daily screen for those dates, you may find there's only summary data.

DeepBreathing,
Thanks for your timely and very helpful reply. Sorry if I should have known the missing detail data causes the bar to go gray. I did several searches here and other places as well, but even though the question seems to have been asked before, I found no clear and helpful answers until your reply.
Researching my machine use led me to notice that for the days in question I had put the SD card back into the machine locked after checking my sleep report in the middle of the night.
All it seems to take to get a gray bar is to have missing detail data for any session that shows up in the summary data.
That explains what I was doing to cause the gray bars. When you make a mistake it is nice to have an indicator like that to help you avoid repeating the same mistake. Of course you have to know what the indicator means in order to benefit from it!
You folks here at ApneaBoard are doing great things to help us all over the little bumps in the road we encounter.
I will be sure to donate as soon as I can.
Keep up the good work, and again, Thanks.

Well, I get gray bars but have full data. But Sleepyhead seem to have a bit of trouble with my night-shifts. That´s when I go to bed at 07:00 and wake at around 14:00. Not all just some. There is usually a bit of white space at the end or beginning of the data. I think that might be what set the gray bar off in my case Smile

I've experienced gray bars before in the latest edition of SH.  Try rebuilding the data (Data->Rebuild CPAP Data->Your CPAP Model & S/N) then exit and restart SH. Mine will usually clear up.

Qualtech -

If you are up to being able to configure a WiFi SD card in your cpap give it a try.  Many of us use a WiFi enabled SD card to wirelessly transmit data to our laptops or PCs.  Using this method you will no longer have to worry about whether your SD card is back in the machine and/or whether the card is locked or not.  

A common WiFi enabled SD card and one that many members here use is the Toshiba FlashAir W-03.  There are 2 programs written by members to configure these cards both of which are excellent and work.

FlashPap - http://www.apneaboard.com/forums/Thread-...t=flashpap
Sleepmaster - http://www.apneaboard.com/forums/Thread-...t=flashpap

Either of these should work and many members are able to successfully configure these cards without being tech savvy.  Of course, should you run into any difficulties there is plenty of help here.

You will need to buy the Toshiba card on-line.  Just search internet for best deal.
