Totally agree. And the weird thing about that is that the original charts on the Crestmont website DON'T do that. The original charts have losses in red, gains of 0-3% in pink, gains of 3-7% in blue, gains of 7-10% in light green, and gains >10% in dark green.
Now, that also "wastes the scale" as you say, but every grid square does have the actual return number in it.
I can understand why the NYT left the actual numbers out of the squares (makes it very cluttered) but they should have used more color "bins" and a more intuitive choice of colors. Very odd on NYT's part.
