In the last couple of weeks I stumbled upon the same Tableau problem three times. Once it was my own problem, afterwards two other people mentioned similar problems. That seems reason enough to try to figure out a solution to it! Imagine the Tableau Superstore data set, you have one …
I just finished my first Hackathon and am still quite excited about the weekend. It’s incredible what 120 people can come up with when they are voluntarily locked in a room (not literally), to tackle problems which are faced by hundred thousands of people! Below is a summary of my …
I recently analysed call data especially focusing on pattern throughout the week. After creating two heatmaps to plot hours of the day against weekday for number of calls and call length, I continued to create marginal histograms for further details. While trying to figure out smart ways to combine two …
It’s this time of the year again; at least in the APAC region. The Tableau Fringe Festival is scheduled for the 17th of August and we (yes I am part of the team this year!) are looking for speakers to make it a great event! Let me tell you why …

A few days around a collection of “Weird but (sometimes) useful charts” was passed through the Twitter community. While many of them have very defined use cases in science, and some of them are plainly ridiculous (I am looking at you Drunken Speedometer) a few might come in handy in some …
Especially for ad-hoc analysis it might be necessary to highlight only certain parts of the data. It is easy enough to call out certain sections with colour or annotations, however you might want to provide the ability to provide a little more information – just in case. With Tableau 10.5 …
Being creative in any way usually comes with the equivalent of a writes block at some point. You don’t know what to create next, what to write about, what new thing you could try. In the world of Data Visualisation there is always a next data set but after 100 …
Over time I collected a whole bunch of useful links related to data visualisation in general and Tableau in particular. For the official Tableau Desktop 1 and Desktop 2 courses I created a collection of these links to hand out after the course for further readings, more detailed explanation and to see …
