Even though Tableau has been round for a number of years now, there is a dearth of books out there to guide new users. To get the most out of Tableau, you don’t want to approach chart making in the same way that you do in Excel. The videos and webinars that Tableau offers are great, …

Slopegraphs in Tableau
In Tufte’s The Visual Display of Quantitative Information, and recently on his blog, he discusses the use of slopegraphs to show change over time. They are highly effective because you have both the text (the reader would likely want to know the individual values), the sorting, and the slope which allows you to understand the …
Case Shiller House Price Index
Standard and Poor’s Case-Shiller index was released today with disappointing indications of a double-dip recession, at least for the housing market. This provided an excellent opportunity to visualize the data they make public. Below is the seasonally adjusted data for March 2011, going back over two decades. The index is set so that all cities …
Exploring Data in a Single Chart
Chandoo’s excellent Excel and Data blog has a data challenge to win a Kindle. I’m not entering but thought I’d show what Tableau can do with just a few hours of work. The challenge was to create a single chart that showed the data story the best. Below is what I think works, but the …

This post deals with helping the user understand there are multiple points overlapping on a regular scatter chart. Tableau simply plots the marks on top of each other and the resulting tooltip shows …
Stem and Leaf Plots (sorta) in Tableau
In some work I do with specific clients, there is great value in charting the raw data and not letting information be hidden by averages or rates. If I have a single measure (for example ‘Number of acres of land owned’ ) I like to show it on a scatter plot with just one axis. …
Tableau: US Map with Alaska and Hawaii
When plotting geographical data in Tableau (and many other packages) you either end up with a map that includes Alaska and Hawaii and therefore much of Canada and the Pacific, or you choose to just show the lower 48, and pretend that AK and HI don’t exist – after all how much oil does Alaska really …
Earthquakes in Japan (last 7 days)
The sheer number of earthquakes that Japan has experienced over the last seven days is astounding, as is the difference in energy between the ‘smaller’ ones and the 8.9. The data is from the USGS. My thoughts are with the people of Japan. Dashboard 1 Powered by Tableau
