How to read the chart colors and the tissue bars (Iris/Drak)
Posted by Support Manager, Last modified by Gianluca Tedone on 22 August 2012 02:43 PM
Moving mouse on single dive step you can access at all the information you need in display area.

Lines are in different colors:

yellow: ascent diving
red: deco diving
magenta: ascent diving in deco dive

The tissues diplayed with the profile (at lower right) represent the limit of accumulated nitrogen in order to a dive with no deco.

Iris/Drak displays the ratio between the nitrogen concentration in a tissue respect the critical content for those tissue. A red tissue represent a critical nitrogen concentration.

So it is possible to exit a dive when all the tissue bars are green.

What do the bars represent? Different tissue types, different body parts, or something else?

Sorry if this is a stupid question - I'm not very familiar with the tissue modelling algorithms.
