I’ve been trying to find out how to do a radar chart in Tableau without using R. I found this this post on The Information Lab which gives a good idea, but is outdated and is not really what I was looking for.
I did some research, and after learning about the new Level Of Details feature in 9.0, I realized I could do it quite easily!
The big idea is you need to first find the max radius fixed on the point – meaning it will find the max value per point and use that for that axis. Then, you just device the value by that, and you get the relative position. Finally, you do some trigonometry, et voilà!
If there is any interest, I’ll get into the details on how to do this soon.
