The Waterfall Widget in Datarails is a powerful visualization tool designed to help users understand the step-by-step changes that drive a value from a starting point to an endpoint. Whether you're analyzing revenue, variance, or any other financial metric, the waterfall widget presents changes in a clear and intuitive format.
This article dives into the two primary modes of the widget: Breakdown Chart and Walkthrough Chart. While they may appear similar at first glance, each serves a distinct analytical purpose.
Breakdown Chart
The Breakdown Chart is ideal for illustrating how a total value is composed of various components. It begins with a base value and breaks it down into its contributing elements. Each bar represents a portion that either increases or decreases the overall total, allowing you to see the composition of the final number.
Walkthrough Chart
The Walkthrough Chart is used to explain how a value changes over time or across scenarios. It focuses on the journey from a starting point to an ending value, detailing each positive or negative driver along the way.
Best Practices and Use Cases

Ideal for variance analysis, especially in FP&A.
-
Break down complex P&L changes over time or period-on-period deltas.
