Above() behaves differently in pivot charts vs. other kinds of charts. Above() finds the row above within the same column segment. In your pivot table, the column segment definition corresponds to what we see visually, so the segment includes all records with the same company. In any other table, the column segment includes all records with the same value for every dimension except for the last one. Since you have the Date occuring before the Company, the column segment ends up being only a single record. That makes above() return null, and since you use above() on every row but the first, every row but the first is null.
In a sense, this is simple to fix - just reverse the order of the dimensions. That does indeed get the right values in the bars. Unfortunately, it also really messes up the display, and I'm not sure how to fix it.
Anyway, knowing what's wrong is at least a good first step.
And as a side note, while this doesn't fix anything, this is how I write expressions that need above. A rangesum substitutes 0 for null, so it keeps you from having to check if you're on the first row.
rangesum(sum(FD_DimInput.BookedVal*_Report_CurrYTDYear*_GrossProfit*_Actual),
-above(sum(FD_DimInput.BookedVal*_Report_CurrYTDYear*_GrossProfit*_Actual)))
