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.

In this week’s Tableau Tip Tuesday, I show you how I created a slope graph that includes vertical lines. I really like the addition of the vertical lines as they add structure to the overall look and keep the viz neatly aligned.
