Shallow dive profile doesn't look too good

[Henrik Brautaset Aronsen]

Here's an example of a shallow dive profile: http://db.tt/mR443Zce

There's a lot of screen estate being wasted here.

Also, for this particular dive, the first air sample was 0, while the 
rest were OK.   So, the start bar ("0 bar") label looks misplaced.
