Blue vs. Green - What does it mean?

No comments

When I first started using #Tableau, I assumed that blue meant dimensions and green meant measures. They don’t.

Blue means Discrete
Green means Continuous

It took me a couple of years to get my head around this most foundational concept in Tableau.

Dimensions and measures are merely a way that Tableau organizes the data.

And if you only take away one thing from this video, this is it:

  • Blue things GROUP your data
  • Green things COUNT your data
  • Dimensions SPLIT up the view
  • Measures FILL the view
I've spent years teaching people what blue and green mean in Tableau and I keep coming up with new methods. In this video, I’ll explain the entire concept to you.

#MakeoverMonday 2023 Week 26: The UK's Drinking Culture

No comments
This week I delve into drinking, a topic that has long been integral to British culture. 

We covered lots during the live stream. I started by attempting to recreate the original, but couldn't get it to work. I went on to build:

1. Stacked bars
2. Stacked bars with labels above the bars (there are a few neat tricks in this one)
3. Circle on a dotted line
4. Donut chart, bar chart combination chart
5. Bullet graphs
6. A mobile view that's a different sheet

Building the mobile view hopefully showed everyone how to leverage sizing objects in a dashboard. If you haven't watched, I created a 2nd sheet that I could format separately to fit on a mobile device. To the user, it would look like the same chart.

The trick is to float the 2nd sheet and make it 1x1 size. Because it's on the dashboard, you can then use the sheet in the mobile view. Check it out, you'll like it.

I'm pretty happy with where I got to in the end. Enjoy the live stream and check out the viz below or here.

#MakeoverMonday 2023 Week 24 - Cereal and the Green Revolution: Yields vs. Land Use

No comments

At the global level, how has crop production changed over the last fifty years? 

In this Watch Me Viz live stream, I analyzed how the yield and land use of producing cereal has changed over the last 50 years.

I really liked the original visualization, so I rebuilt it in Tableau. I learned how to use dynamic zone visibility, layout containers, and more. Check it out.

2. Final Dashboard -


Watch Me Viz is a weekly live stream where I help people become better at #Tableau, #PowerBI and data analysis. I show how I take an existing visualization, critique it, analyze the data, and build several visualizations all the while looking for a "better" visualization than the original.

If you are considering participating in Makeover Monday, you can get started by downloading data sets from the Makeover Monday website. I promise you'll become better at data analysis and data visualization by practicing every week.
