Waterfall Charts

Waterfall charts help to convey how an initial value is affected by a series of intermediate positive or negative values. They are particularly useful for understanding the gradual transition in value of an item that is subject to increment or decrement. Whole columns represent the initial and the final values, while the intermediate values are expressed as floating columns. The columns are color-coded to distinguish between positive and negative values: green for positive values; red for negative; and blue for totals. Additionally, cumulative (a column that shows the sum of all columns to its left) and non-cumulative (a column that shows the sum of all columns to its left, after the last cumulative column) sum columns can also be rendered.
