Thanks for working on this.

Looking through the patches I don't see any red flags (but haven't done a
detailed review, yet).

On the visualization side... I wonder if this is as helpful as it could
be. It has SO MUCH information...

When I first envisioned this I thought it should give the user the data
for ONE point in time - just like the info overlay. So as you move the
mouse, the data changes, the bar graph changes. Which makes it more "like
the Petrel" and maybe makes it easier for the user to absorb the info. And
as you move the mouse it gives you the "movie" effect if done right.

What do you think, would that improve the usefulness?
