Question

what is a waterfall chart​

Answer 1

A waterfall chart shows a running total as values are added or subtracted. 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 còded so you can quickly tell positive from negtive numbers.

Waterfall Charts are used to visually illustrate how a starting value of something (say, a beginning monthly balance in a checking account) becomes a final value (such as the balance in the account at the end of the month) through a series of intermediate additions (deposits, transfers in) and subtractions
