Stacked column chart with 3 values, one of which is negative, with ~30 columns.

[cpollard]

I'm trying to create a stacked column chart with 3 values, with both neg & pos values for ~30 data points.
Example:
A: +$12, +$0, +$20 = $32
B: -$5, +$0, +$33 = $28
C: -$17, +12, +$2 = -$3
D: -$38, + $0, +$21 = -$17
