Thomas Lüthi

After a master’s degree in English and Business Administration at the university of Bern, Switzerland, Thomas worked as a linguist and actor before joining the Data School. Fed up with endless auditions and nonsensical machine translations, he decided to focus his creative energy on a new career path. When he came across the Data School, he knew he had found the perfect place to combine his passions for storytelling and information technology.

Throughout his career he kept a creative outlook on the world, finding new approaches to problems and presenting his work in a manner that engages his audience. The joy of finding new insights, breathing life into numerical data and making complex issues easy to grasp is what got him hooked on Tableau.

In his private life, Thomas is a jack of many trades although his mastery is questionable at best. He loves language, history and the creative arts and he likes to think of himself as a decent cook.

Bye-Bye, 25WS

Structuring Word Clouds

Word clouds don't have the best rep, but they can be a powerful tool to represent text-based data. There are tons of great manuals for how to build a word cloud in Tableau, so I won't get into the details about that here. One thing I will say is that with word clouds,...

A Tableau Visualisation of the Whole American Civil War

DS11 Dashboard Week Day 5: Boyz Boyz Boyz!

DS11 Dashboard Week Day 4: I Want to Ride my…

After our excursion into the new, eciting, sometimes confusing, often just plain wierd world of Power BI, we were back in our native Tableau for our second to last Dashboard Week Challenge. This was another data set from the US (it's like nothing interesting ever...

DS 11 Dashboard Week Day 3: I Got the Power

Try Something New! It was hump day for DS11's dashboard week today, reason enough for Andy to mix things up a little and drag us (some of us willingly, some less so) out of our comfort zone. The task for today was to visualise a data set on money paid to US higher...

Transparent Worksheets in Tableau

There is a feature that was released with Tableau 2018.3 which can make designing dashboards a whole lot easier, but which might also lead to horrible creations, floating containers and confusion: Transparent Worksheets! Until recently, going to the format section and...

Throwback to DS Week 1: Application Reviz

This post has been on my laptop as a draft for weeks, and I had been meaning to finish and publish it forever. After Andy and Eva gave a talk at the Data School about being more productive and mentioned how they never keep a blog post in draft, I decided to finally...

Setting Reference Bands with Custom Values per Pane

Using Multi-Row Formula to Rank Records in Alteryx

A challenge I encountered when coming to grips with Alteryx was to rank records based on a shared value. For this exercise, we are trying to rank players according to their score. Simply sorting and ranking the records would give players with the same score different...
