PART 2 In part one we familiarised with Tableau's automatic Trend Line, information provided and inferences possible. Now I want to focus on the fun part: how to calculate the trend line ourselves using Tableau-R integration as well as two applied examples "How much above/below ?" and "What if"....
Last summer, I was invited to speak for the Boston Tableau User Group at the Broad Institute. This was a different crowd, composed of mainly scientists. There were two Zen Masters in attendance: Chuck Hooper and Jonathan Drummey. Prior to my speech, I had the good fortune to see Nicole Nichols,...

After completing my first book, I enjoyed traveling all over North America and Europe speaking at companies and Tableau User Groups. A big part of the fun was meeting hundreds of Tableau users. One of the first user groups to contact me to ask if...
Hot topics in the world of Big Data are forecast and trend models, and Tableau has integrated both features. All it takes are two clicks, and a trend line appears - your viz instantly looks more interesting. The disadvantage of the automatic trend line is...
Donut Charts bieten einen schnellen Überblick über Datenfelder mit wenigen Dimensionen. Im Wesentlichen bestehen sie aus berühmt-berüchtigten Pie Charts mit einem zusätzlichen Kreis in der Mitte – nichts Besonderes, dennoch schnell zu erstellen und richtig eingesetzt sehr nützlich und informativ. Die Segmente eines Donuts eignen sich hervorragend...
