the problem I see is that we need that information in the diveProfileItem which gets its data from the divePlotDataModel. And that has random access not sequential (at least in theory). And, what are two ints amongst friends? Or do you have another suggestion how we can tell the DivePercentageItem::paint what the current inert gas fraction is?
