I agree, a very effective display. Tukey's boxplot has a more or less robust estimate for the disperson, which can't be said for the min/max ranges (apart from being averaged values ...)

Still an extraordinary chart!

Tommy McCall

I was delighted to see my chart complimented, for the most part, here. I like the dot-plot idea and agree the lines linking the left edge are redundant. I'm not sure I understand the problem with showing the range of average incentives. If the current average was a good number, then why not the other ones?

Tommy, the NYT should be putting your name to graphs like this, the same as they would for the writer of a story or the photographer who provided a picture.

Excel won't do it, so I did. The following page links to procedures that will produce decent box and whisker charts, and describes a utility to do it for you (the utility is still in development, but works nicely):

Hi Tommy, great to see you here. Derek is right: it'd be great if the newspaper acknowledged your work, and the time and care needed to produce good charts like this.

On the question of the averages, I could be misinterpreting what you're plotting. What's the data used to plot that "average incentive" row?
