distribution of scores in short list not matching data

Per Chris Wong: I noticed it when tinkering with the "apply threshold" slider controls. I noticed that the display of the distribution doesn't match the change in colors when I move the sliders. I took a look at the actual score data for the attribute and saw that the scaling of the display does not match the data. I made a screenshot to show what I'm talking about. You can see that the distribution in the short list is shown incorrectly skewed toward the "8.4" side.
