@Co the nitrogen levels in the tissues of my body. Left/top most bars are slow tissues, cells directly adjacent to cappilaries, right/bottom most are slow tissues (ones that need to diffuse through several layers of tissue). The height of the bar indicates the concentration. In this picture my fastest and slowest tissues are about equal to ambient n2 while my mid range tissues have some saturation and are off gasing their nitrogen.
Yea green is ambient, so on the surface after a day they would be flat and green. But the chart changes at depth. Like if i dove with the bars like this all the yellow bars would go green and shrink when i dove and reappear if i surfaced again
They are generated by algorithms. The watch uses buhlman algo, the square computer is using the variable permiability model with gradiant factor (VPM+GF)
