Waterfall bar chart

A waterfall chart is a form of data visualization that helps you to understand the cumulative effect of sequentially introduced positive or negative values. 

Each element of the selected category is represented by a bar, which is color-coded to distinguish between positive (green) and negative (red) values. Each bar is placed at the level of the cumulative value for all previous elements. The width of each bar represents the value that corresponds to the respective element. The relative position of the bar corresponds to the cumulative value. The last bar represents the sum of all elements that are displayed.
