How I Create a Unit Histogram in Tableau

No comments

A unit histogram is a chart that shows the distribution of data points across a series of bins of a measure.

Unlike a traditional histogram that uses bars, a unit histogram consists of a set of marks, each representing a member of a dimension. 

In this example, our final result is a unit histogram showing the distribution of states by their average sales.

How to Create a Comet Chart in Tableau

No comments
A comet chart is a type of visualization used to display the trajectory of data points over time. 

They’re often used to compare one time period to another to see the direction of the change.

The tail starts at the first time period and grows like a comet to the second period.

Jumpy Curvy Things in Tableau

No comments

I received a request to teach how to build a jump plot during Next-Level Tableau office hours. The idea was to recreate this visualization that I created for Makeover Monday back in 2018.

The problem, though, was that the data preparation was done in Alteryx, which I no longer have a license for. Thanks for a member of NLT that had an Alteryx license, we were able to decode what the workflow was doing.

Then, in office hours, we recreated the data prep in Tableau Prep before building the visualization in Tableau. Download the Prep flow here. Download the workbook below.

This is just one example of one thing learned as a member of NLT. Sign up today and I guarantee you'll become a Tableau expert.

How to Create a Donut Chart in Tableau

No comments
Make your data delicious with this Tableau donut chart tutorial. 

Donut charts are a common way of showing part-to-whole data – but be aware that it’s difficult to accurately compare the size of the segments. 

They are similar to a pie chart – but the centre can be a good way of making space to include more information about the data (e.g., total).

Which chart would you like to show?

Beginners and advanced designers alike get stuck deciding which chart is right for their data. Next time you're stuck, try this chart guide by Damola Ladipo.

#WatchMeViz: Can viral infections be cured with antibiotics?

No comments
I'm really surprised, though maybe I shouldn't be, about the results from a poll of 1206 Americans by KFF. They asked a simple question: 

"Can viral infections usually be cured by antibiotcs, or not? Or do you not know enough to say?"

According to the results, women know better than men, as do adults with higher incomes and higher levels of education.

I took on this data set for Watch Me Viz for Makeover Monday week 14. Check out my final viz here. There's an image below the video.
