Here's the link to Simon Mitchell's talk, where the idea came from:

I've now taken a look at these graphs and I really like what i see.

One opportunity for improvement is the color scale. I rather liked Simon
Mitchell's scale with light blue -> purple -> down to black for tissues
taking on gas, and black -> green -> yellow -> red for supersaturated
tissues off gassing. Those feels like they have a more intuitive

Another thing which would be really nice is to fix it so you can zoom
into the heat map plot without it "splitting" into 16 different bars.
We might need someone with a better Qt magic wand here. Tomaz? =)
