We previously had an article about creating Shaped Bar Charts in Tableau; in that previous tutorial, we used data densification to create a different look and feel for our bar charts. In this tutorial, we are going to explore using 3D shapes to create 3D Bar Charts in Tableau.

Note: 3D data visualisation is not considered best practice for data visualisations, however, I have seen these used to create interesting and engaging infographics or used for infotainment.

## Data

``````Country,Value
United Kingdom,100
United States,80
France,60
Germany,50
Italy,30
Australia,70
India,50``````

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:

``````Path
0
100``````

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 shapes 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 Bin and Calculated Fields:

Path (bin)

• Right-click on Path, go to Create and select Bins…
• In the Edit Bins dialogue window:
• Set New field name to Path (bin).
• Set Size of bins to 1.
• Click Ok.

Index

``100-INDEX()``

TC_Value

``WINDOW_MAX(MAX([Value]))``

Rows

``````IF [Index] <= [TC_Value] THEN
[Index]
ELSE
NULL
END``````

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

## Worksheet

We will now build our first worksheet:

• Change the Mark Type to Shape.
• Drag Country onto the Columns Shelf.
• Drag Country onto the Marks Shelf.
• Drag Path (bin) onto Columns Shelf.
• Right-click on this object and ensure that Show Missing Values is selected.
• Drag this object onto the Detail Mark.
• Drag the Rows Object onto the Rows Shelf.
• Right-click on this object, go to Compute Using and select Path (bin).

If all goes well, you should see the following:

We have now created our Shaped Bar Chart, but now we will need to download, unzip, and add copy the following shapes to our Shapes directory. If you have not done this before, check out our article on Custom Shapes.

Note: These are cube objects that I have created and colored using Material Design colors.

• Set Grid Lines to None.
• Set Zero Lines to None.
• Set Axis Rulers to None.
• Assign our Cube Shapes to each Country.
• Click on the 254 nulls and select Filter.

If all goes well, you should now have the following final data visualisation:

Exercise: Explore with our own objects, and let me know what you come up with.

and boom, we are done! I hope you enjoyed this tutorial, and as always, you can find this data visualisation on Tableau Public at https://public.tableau.com/profile/toan.hoang#!/vizhome/ShapedBarCharts3D/ShapedBarChart3D

1. Hi Tableau Magic, I applied the same steps on sample super store data where I am using sales and subcategory to create 3D bar chart but in my view all the bars are same in height..how can we fix this ?

• Hi Imran, it sounds like you are not setting the Table Calculations correctly. Right-click on the Y axis pill and go to Edit Table Calculations and adjust accordingly.

• Imran, actully the thing is if u use sales by subcategory it wont as any of the sub category have more than 100 then it will appear as full bar, so that that u need to use this ({fixed: sum (sale )}/sum(sales))*100. To make each category as percentage number which will be below 100 for sure

2. Hello Toan, thanks for the all the helpful posts. was trying the 3d bar chart with a different data set where I am showing “Aging groups”. However, bars are not starting from the x axis. I see floating cubes, any idea why?

3. hi Toan can we do this 3 D charts only if source data is excel? or it possible with other sources too, I am using a BI report which is a hyperlink. when I try the first step at joins its failing.

4. I am using Tableau 2020.2.7. In this version there is no concept of Join. But there is a relationship. and 1 =1 , in a relationship does not work. Can you help me here, Super urgent
