It's useful for understanding how an initial value (for example, net income) is affected by a series of positive and negative values. The columns are color coded so you can quickly tell positive from negative numbers. The initial and the final value columns often, while the intermediate values are floating columns. Because of this 'look', waterfall charts are also called bridge charts. Tip: Use the Design and Format tabs to customize the look of your chart. If you don't see these tabs, click anywhere in the waterfall chart to add the Chart Tools to the ribbon.
Waterfall charts have emerged in PowerPoint for Mac after a recent software update. This would be a major addition, since these types of charts are highly useful to summarise changes in data.

Start subtotals or totals from the horizontal axis If your data includes values that are considered Subtotals or Totals, such as Net Income, you can set those values so they start on the horizontal axis at zero and don't 'float'. Double-click a data point to open the Format Data Point task pane, and check the Set as total box.
