RE: graph
a little hard without more of an explanation.
probably you are looking at the AHI for the whole night (single number) and then a graph of the hourly AHI going up and down thru the night on the bottom. true AHI is total events divided by the total time (in hours). 27 events in 6 hours yields and AHI of 4.50. At the very top of graphs, I think that one is the AHI calculated over the period that is displayed only. If I zoom into a 1 hour and 55 minute section, and count 14 events in that section, AHI there is 14 divided by 1.9 hours = 7.36.

RE: graph
Could it be AHI and RHI?
