SleepyHead Graph display problem
When I first loaded SleepyHead, the graphs looked OK. Now the displayed graphs are not displaying the information along the Y and X axis's correctly and I can not find a fix. Please look at two screen examples here (jpg photos):


Anyone have this same problem or suggested fix?

Right click on the daily graphs and reset graph layout. If other anomalies are present, you can use the menu item Data to rebuild CPAP data. This appears to be a graph layout problem.

do you have an Intel-chipset-graphics-card by any chance?

use the broken-GL.exe ... it should be somewhere around "C:\Program Files (x86)\SleepyHead\SleepyHead-BrokenGL.exe" (you really get used to it after the second time^^)

(yeah, I can imagine that the open-GL so far worked without problems - might also in the future - looks really like an "open-GL" thingy - the broken-GL version should ALWAYS work as supposed to and should fix your problem instantly and completely!)

I get no response when I right-click on the "Daily" tab, either at the top left, the "Daily" icon in the navigation bar on the right, or on any graph. Maybe I am not understanding the instruction here. I had already tried the "rebuild CPAP data" menu from the DATA tab before I posted today, and again just now. I also tried the "Reset Graph layout" from the View tab but got nothing here either.

 I am studying the suggestion offered by TBMx and will post the results. The graphics card is a Dell stock Intel® G41 Express chipset video card. If you look at my previously posted graphs from Sleepriders reply #14, to my “Un-happy face sleep report” post, or at ( http://imgur.com/a/VWHBw ), you can see that it was working OK then. I will try the broken-GL.exe and see what happens.
Thanks, Joe

Although I got this message, running the broken-GL.exe file worked instantly. Thanks.

Ok, I think I got it figured out. There are two .exe files in the SleepyHead program folder of C:\Program Files (x86). The shortcut installed by the Sleepyhead install, calls C:\Program files(x86)\SleepyHead\SleepyHead.exe and runs. But my version is now failing to display my graphs correctly. As TBMx pointed out, the broken-GL version of SleepyHead.exe will work-a-round this problem. I don't know what the real fix is but my Norton anti-virus protection program won't let me download and install a fresh copy of Open-GL; but running the C:\Program Files (x86)\SleepyHead\SleepyHead-BrokenGL.exe works. If you have this problem, you can right-click on the desktop SleepyHead Icon shortcut, then, choose properties, then add "-BrokenGL" to the link shown in the shortcut (or delete and enter the full path "C:\Program Files (x86)\SleepyHead\SleepyHead-BrokenGL.exe", to load and run SleepyHead.   

This also fixed another problem I was seeing. As I would scroll down the graph page, the displayed graphs would black out, then reappear as the page scrolled. A problem another poster had an issue with too. This may very well fix his problem too. Joe

from what I can tell this problem arises only in the specific combination of:
windows + intel-chipset-geraphic + sleepyHead. (I haven't heard from anyone else needing the broken-GL version)

the very same graphic-chipset runs fine on linux (OK - not all of them) - so this has to be a driver problem. not all intel-graphic-chipsets are affected - the newer ones seem to work fine. these cards are all capable of open-gl-support (which SH states correctly on the first start of the broken-GL) but due to intel not updating the drivers for chipsets and thus beeing stuck with an not so up-to-date reference driver from microsoft your are left with such behavior.
(so there is actually nothing you can do as an end-user to fix that - other than using the broken-GL - trying to get the newest chipset and graphic driver is always a good start - but don't get your hopes up)

what makes it even more odd is the fact that it may run a very long time without any problems. As the "real" open-GL version runs without any problems on 'new' and fully open-gl-capable cards it seems that this is not a "real bug" in sleepyhead - but an intel-problem, meaning intel's implementation of open-gl.

As I'm stuck in exactly the same situation I do as follows:
I use the "normal open-GL" version always - even if the display glitches show up - the program itself and the import work! - it's really just a display-glitch.
whenever these glitches show up I close down sleepyhead (not killig it - closing it the usual way!) and reopen my profile with the broken-GL version and keep on doing where I left.

(A complete restart of windows (complete as in contrast to "fast startup") fixes it for a while as well; having graphics intense programs open at the very same time as sleepyhead do make the glitches worse^^)

I had had a problem with my Summary graphs locking up.
This resolved that issue.

I am having the graph display problem but the fixes recommended did not work.  I don't see the graphs at but on the overview tab I do see data in tabular format.  Any suggestions on now to fix?

I'm using the surface book and windows 10.
