This is a quick tutorial on creating a Radial Column Chart in Tableau. I have seen so many interesting ways that this has been used, so I really hope you enjoy this quick and simple tutorial.

Note: This is an alternative type of data visualisation, and sometimes pushed for by clients. Please always look at best practices for data visualisations before deploying this into production.


We will start by loading the Sample Superstore data into Tableau.

Note: If you have Tableau Desktop, you can use the Sample data source, but if you are using Tableau Public, download and load the following data source.

Once your data is loaded into Tableau, right-click on the data source and click on Edit Data Source… with the Data Source Editor open, paste the following:


Note: If you are using Tableau 2020.2 or great i.e. have access to new Relationship Model, you will need to double-click on the originally pasted data source to open up before pasting in the Path Data.

You should get an error as there is no joining column, however, click on Add new join clause, go to Create Join Calculation, type 1 and click OK. Do this for the right-hand side as well. Ensure that you have Inner join selected and you should see the following:

Note: we need additional records as we are going to be drawing lines and using densification to get more points on our canvas. For more information, check out our article on Data Densification.

Calculated Fields

With our data set loaded into Tableau, we are going to create the following Calculated Fields:







TC_Total Sales


TC_Percentage of Total Sales

[TC_Sales]/[TC_Total Sales]


[TC_Percentage of Total Sales]/WINDOW_MAX([TC_Percentage of Total Sales])

TC_Step Size


This nifty calculation spaces our lines so that each line is evenly distributed around the circle. This takes into account the total number of Dimensions so is dynamic.


IF MAX([Position]) = 1 THEN
    SIN(RADIANS([Index]*[TC_Step Size]))
    SIN(RADIANS([Index]*[TC_Step Size]))*(1+[TC_Distance])


IF MAX([Position]) = 1 THEN
    COS(RADIANS([Index]*[TC_Step Size]))
    COS(RADIANS([Index]*[TC_Step Size]))*(1+[TC_Distance])

With this done, let us start creating our data visualisation.


We will now build our first worksheet:

  • Change the Mark Type to Line.
  • Drag Position onto the Path Mark. Ensure that this is a Discrete Dimension.
  • Drag State onto the Detail Mark. Remove the Country Pill.
  • Drax X onto the Columns Shelf.
    • Right-click on this object, go to Compute Using and select State.
  • Drax Y onto the Rows Shelf.
    • Right-click on this object, go to Compute Using and select State.

If all goes well, you should now see the following:

We will now adjust the Table Calculation to get what we are looking for:

  • Right-click on X and go to Edit Table Calculations.
  • In Nested Calculations select TC_Sales.
    • In Compute Using select Table (across).

You should now see the following, how simple was that?

Now we will adjust the Cosmetics:

  • Hide the Headers.
  • Hide the Grid Lines.
  • Hide the Zero Lines.
  • Adjust the Size.
  • Adjust the Tooltip.
  • Adjust the Color.

You will want to end up with something like the following:

and boom, we are done! I hope you enjoyed this tutorial, and as always, you can find this data visualisation on Tableau Public at!/vizhome/RadialColumnChart/RadialColumnChart

  1. Hi Toan,

    How is TC_Distance calculated? I can see it under X and Y calculations but don’t see a separate calculation for TC_Distance. Thank you for this tutorial.
