A Power BI waterfall chart is also called a bridge chart. It uses a series of continuous vertical bar columns showing the profit (gain) or loss. The columns in this chart are color-coded, where green represents the increase (positive), red means the decrease (negative), and blue for the total.
Power BI Waterfall Chart is very useful for visualizing the Sales or Profit over some time. Let me show you how to create a Waterfall Chart with an example.
When to use Power BI Waterfall charts?

Waterfall Chart FAQs
Click on the Waterfall icon under the Visualization will automatically create a dummy. In addition, adding a Numeric measure (Profit or money spent) to the y-axis and a series or dimension to a category section generates the actual waterfall chart. For example, if you add another dimension to the Breakdown section, it will explore the details of the bridge chart.
Adding any hierarchy to the category section will enable drill-down action—for instance, date hierarchy or geography.
In general, Waterfall charts show the profits over time or running totals. These charts help to understand the positive and negative outcomes of the changes.
Under the Visualization pane, click on the Format your chart option. Next, toggle the Data labels option On. Furthermore, you can format the color, font style, and size and display units to thousands, millions, etc.
