#TC18 – not your ordinary conference!
#TC18 ended more than a week ago and by now I had some time to reflect the experience attending my first Tableau Conference. It was a great experience and I plan to attend again next year, so much is clear! It wasn’t only my first Tableau Conference, it was my …
Men(tor|tee)s in the Tableau Community
There is lots to digest and think about after last weeks Tableau Conference and I still plan to write down a summary of my experience. One thing I wanted to write down before however were my thoughts on “Mentorship” because it was kind of a red thread through some of …
Put yourself out there at #TC18!
I haven’t been to a Tableau Conference (yet) so for specific tips you might rather want to head over to Sarah’s blogs. I do attend all kinds of smaller events though and while the scale is different, the fundamentals of meeting people still apply! There are two main things to …
Analysing open orders per day

While trying to figure out smart ways to combine two …

Triangles in Data Visualisation

Andrew Eberhard, the lecturer, asked me to talk about myself and my background, my job and the industry, data visualisation in general and Tableau in particular. It was a bit strange to actually describe …
