The N2 button toggles display of the nitrogen partial pressure. But it
does not toggle the display of the ceiling and tissue compartment
loading (this is controlled by another button on the dive profile panel,
the one with the diver and the up-arrow). If the gradient factors are
shown above the profile, then it means that display of the calculation
of nitrogen loading at the tissue compartment level is switched on. On
my machine, the NDL remains at the maximum level (120 min) throughout
the dive, no ceiling appears and Robert's tissue loading display (at the
bottom of the panel and in the information box) shows NO tissue loading
at all. Yet, the XML dive log shows strong tissue loading and looks much
more realistic to me. I suspect it is just a variable that needs to be
set somewhere, but I am clueless.
Kind regards,
