CDC should know better.
P.S. In comments, Zachary David supplies this correctly-scaled version:
It would be better to label the lines directly than to use a legend, and the y-axis is off by a factor of 100, but I can hardly complain given that he just whipped this graph up for us.
The real point is that, once the x-axis is scaled correctly, the shapes of the curves change! So that original graph really was misleading, in that it incorrectly implies a ramping up in the 3-10 year range.
P.P.S. Zachary David sent me an improved version:
Ideally the line labels would be colored so there’d be no need for the legend at all, but at this point I really shouldn’t be complaining.
