Things that I have learnt or discovered that help me with Tableau
I didn’t manage to finish my “What’ the Harm?” dashboard in time for #IronQuest or with any degree of polish, but I did manage to come up with a new (at least for me) chart type: the hex spiral unit chart. I’m not sure it has that much data visualisation value, but it looks kind of pretty! This article describes how to build one: Background and alternative approaches For my What’s the Harm dashboard, it was critical for me that…
After the recent Workout Wednesday polygon exercises, which relied on calculating x and y coordinates, I decided to try my first radial diagram. Can’t be that difficult, right? Actually, it was pretty easy! It just needed a bit of clear thinking about the calculations. Before I get into how it was built, you can see it on Tableau Public and below: Back to school – Trigonometry Full disclosure: I LOVED this stuff at school! And still do. I created the…

There’s a great mystique around the whole area of table calculations with LODs having stole a lot of their limelight. They range from very simple to incredibly difficult to get your head around. I’m still at the beginning of my discovery, but I wanted to share a tip about how some of the basic concepts started to find purchase on my neurons. I simply created the table below from the Superstore dataset, added SUM(Sales) to the table and used the…
