From e1019cafa87058562d9f5844619841546029a57c Mon Sep 17 00:00:00 2001 From: Dirk Hohndel Date: Sat, 19 Nov 2011 14:39:35 -0500 Subject: [PATCH] Improve tank pressure sac coloring This changes the algorithm that picks the sac color to consider +/- 1 l/min to be the same color (before the color changed every time you crossed above or below the average which looked silly with our synthetic "constant sac" values as those are discrete and oscilate around the average. This also changes the order in which things are drawn so so that the pressure plot goes over the depth profile plot (so the red shading of the dive no longer changes the color of the tank pressure plot).
