In our typical waterfall charts, intermediate values and running sums are all positive. We started here with a smaller Income, to allow some intermediate values and totals to go below $0. Last grand total will go back to the X axis as usual, but coming from a negative amount. Negative values cannot be displayed with an alternative (red) color, because alternative colors are usually reserved for up/down variations in this type of chart. Turn Alt Colors switch OFF to show all red bars in green.
