A little more sleuthing revealed the answer. ColumnSet has a method
called formatDataTip (an override) where the percentage is calculated
as follows:
percent = Number(item.yValue) - Number(item.minValue);
percent = Math.round(percent * 10) / 10;
Since I have access to the same minValue in my dataTipFunction, I can
do the same.
