The Big Beautiful Bar Chart: Build It in Tableau with Map Layers

No comments
In this video, I show you how to build what I call the Big Beautiful Bar Chart in Tableau. It combines colored bars, a budget reference line, donut charts, and clean labels all in one view using Map Layers. It looks stunning and it tells a complete story.

Here's what you'll learn:

- How Map Layers work and why they unlock chart types Tableau can't build any other way
- How to set up your data with a five-point scaffold to draw filled rectangles as bars
- How to use LOD expressions instead of table calculations (and why it matters for Map Layers)
- How to add a dotted budget line, sales labels, region labels, and a percentage label as separate layers
- How to control mark interactivity, opacity, and alignment across multiple layers

By the end, you'll have a chart that looks like it took hours but follows a repeatable process you can apply to any dataset.

If you can build this, you're already operating at a high level. Next Level Tableau is where analysts like you go to push further, work alongside the best in the datafam, and get direct access to live training with me every week.

Build a Marginal Histogram with Map Layers in One Sheet

No comments
Most Tableau analysts have never heard of a marginal histogram — and even fewer know how to build one. In this video, I'll show you how to create this advanced visualization from scratch on a single sheet using Tableau's map layers feature.

This technique uses the "Flat Earth" concept to treat your entire canvas as a coordinate system, letting you draw fully custom polygon shapes — no extensions, no workarounds. We'll build a heatmap with bar charts on two axes simultaneously, all driven by calculated fields and LOD expressions.

We're using Trump's Truth Social posting data as the dataset, but the technique works with any time-based data you want to analyze by day and hour.

What you'll learn:
- How Tableau's map layers work and why they unlock charts that don't exist natively
- The Flat Earth coordinate system — how to turn any data into drawable polygons
- Building rectangle polygons using 5-point path calculations
- Creating marginal bar charts (vertical + horizontal) on the same sheet
- LOD expressions to normalize bar lengths across dimensions
- Cleaning up the view: hiding headers, labels, and axes for a polished final result

How to Create a 3 Level Scatterplot Drilldown

No comments

If you want to drilldown multiple levels in a scatterplot, this tip is for you. In this tip, I show you have to create a 3 level drilldown with a scatterplot.

Naturally after I showed how to create a 3 level bar chart drilldown, someone immediately asked how to do it with a scatterplot. Unlike the bar chart drilldown, the scatterplot will only show you marks for the current level. 

For example:

  1. When I’m at the highest level, I see only regions.
  2. When I drill down one level, I only see States within the Region selected
  3. When I drill down one more level, I only see postal codes that are within the region and state I selected.

This example shows you how to drill down from Region to State to Postal Code. To use this for yourself:

  1. Download the workbook
  2. Copy all of the calculations into your workbook
  3. Swap out the dimensions

Note that you will need to recreate the sets and set actions. This will work with any combination of 3 dimensions.
