Yeah, we tried a couple. Those heatmaps I think are quite hard to read.. because it is natural to want to take marginals, but you can't easily do that visually.

I think this whole "octile plot" thing turned out quite nicely. It's in a sense a way of 'slicing' the CDF into 8 even strips and projecting them onto a single axis. It's quite intuitive to read, too. Facebook seems to use it too for some of their papers.
