After Anton's current PR dealing with PSCR code has been pulled, I plan,
as a SECOND step, to incorporate (again) the display of OC_pO2 with the
PSCR pO2 graph. OC-equivalent pO2 has a role very similar to setpoint
for CCR dives. It allows the evaluation of the pO2 drop over the gas
injector, probably the most important gas management activity for PSCR.
Taking into account Anton's strong preference that the setpoint variable
should not be abused for PSCR dive profiles, my plan would be:
1) Create a new PartialPressureGasitem element, starting with the qt
diveplotmodel and using createPPgas() in profilewidget2.cpp
2) Contol its display by setting its setVisible attribute.
Does this sound like a useful approach at all? In this way the setpoint
variable is not involved at all.
The THIRD step would then be to implement bailout events and display gas
pressures as a function of whether the diver is on the loop or on
bailout. This would probably affect the CCR code as well. There is a
separate thread (part 2) on this topic on this mail list.
Does this approach appear at least semi-useful?
Kind regards,
willem
