Radar Chart in Tableau without R

Michel Roberge

Hey guys,

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a radar chart in Tableau without using R. I found this this post on The Information Lab which gives a good idea, but is outdated and is not really what I was looking for.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.

Hi there!

I have been setting up a Tableau Server sandbox on my personal systems, and I wanted to put it to the test. It’s a pretty silly / simple dashboard, but it can be quite interesting and tells a little story about myself.

Obviously, there’s nothing too awesome about the chart itself, but it shows the integration and the simplicity of it. In this case, there’s obviously not much security around it, but for the purpose, I guess it’s all right.

Tableau? What’s that?

If you stumbled here by mistake (or out of curiosity or both), then you might be wondering what IS Tableau.

Tableau is a product made by Tableau Software which allows people to visualize their data. This means putting the data on charts; all kind of charts; and to interact with the data. It’s fast, fun to use, can analyze any kind of data (you can even build your own connectors!), interact with the data, share your insights instantly, and even connect to real time data.

If you wish to learn more about the product itself, I recommend you to start there.

There are a few pieces to the whole thing:

  • Tableau Desktop is the tool to build workbooks (content)
  • Tableau Server is the server to host these workbooks
  • Tableau Public is a desktop/server combo that is public, you can host your workbook there (think cloud), but it’s also visible by everyone, so no confidential data there.
  • There’s a mobile version (ipad and Android) which allows you to view /edit server content.
  • There’s also another version in development, called “Elastik”, which is a tool meant to allow users to analyze anything quickly on mobile devices.

 

I am involved and interested in Tableau products because I integrate an OEM verison of these tools with the flagship product of the company where I work.
