I have used waterfall charts sparingly throughout my career in small business finance. Yet, when Quantrix released its waterfall chart feature in early 2026, I was intrigued to see how it would work. One word: impressive. Also, it’s simple to customize.

I didn’t state this in the video, but this chart only supports one column of data. If you add a second, nothing will be rendered in the chart pane.

The Stephen Few Shoutout: In the video, I referenced an old friend. Well, I never met him, but I own every book he published. Should we care what this retired dataviz expert has to say on waterfall charts? Maybe, maybe not. As the modeler, you know what’s best for your user, so follow your instinct. But if you are curious, check out page four of this document.

A Quantrix Development Team Shoutout: One word: Wow. I write that because this is truly a one-step process. Customization is simple and a breeze. And I know this coding was not a walk in the park. Plus, Tableau does not offer this one-step setup (though it’s easy to create in multiple steps).
