Understanding the Mechanics of Waterfall Charts

Visual Storytelling of Data Transformation

A typical waterfall chart (or cascade chart) starts with an initial value and shows how subsequent additions and subtractions impact the final result. Each bar represents:

• Starting point or baseline value

• Incremental increases (typically shown in green or positive colors)

• Decremental changes (typically shown in red or negative colors)

• Final cumulative value
