That makes more sense. It’s still horribly non-intuitive. In particular, I don’t like the “qualitative” background shading technique, because it makes it appear as if a “satisfactory” performance is all of bad, good and satisfactory at the same time. Why not simply mark those thresholds under the scale of the x-axis? The background shading is disproportionately distracting, considering what little information it encodes.
That said, I can see maybe it would help when you are stacking multiple of these on top of each other and each has its own qualitative ranges.
This actually makes a lot more sense now. I was trying to figure out how this wins in comparison to a standard bar graph with markers. It says information density in the OP, but it never gives an example of how it consolidates information without obscuring it.
Animated it would be useful for an air/fuel gauge project I’m working on for a track car.
