Since releasing our popular Satellite Chart Tutorial, see Drawing Satellite Charts and Variations in Tableau, I have received numerous request for help in creating a layered version of this chart, or an Orbit Chart. As such, in this tutorial, we will go through the process of creating an Orbit Chart in Tableau.

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 into production.

## Data

Load the following data into Tableau Desktop / Public.

Note: we need two records for each Country 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, Bins and Parameters:

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.

Distance from Center

Create the following parameter with:

• Set Name as Distance from Center.
• Set Data type as Integer.
• Set Current value as 3.
• Set Allowable values as Range.
• Set Minimum as 3.
• Set Maximum as 10.

Index

``INDEX()-1``

TC_Percentage of Sales

``WINDOW_MAX(MAX([Percentage of Sales]))``

TC_Rank

``RANK_UNIQUE([TC_Percentage of Sales],'asc')``

X

``SIN(RADIANS([Index]))*([Distance from Center]+[TC_Rank])``

Y

``COS(RADIANS([Index]))*([Distance from Center]+[TC_Rank])``

Size

``````IF [Index]>=(360*[TC_Percentage of Sales]) AND [Index]<(360*[TC_Percentage of Sales])+1 THEN
[TC_Percentage of Sales]
ELSE
0
END``````

So now that we have created a lot of Calculated fields, we will now put this together into a Worksheet.

## Worksheet

We will now build our worksheet:

• Change the Mark Type to Line.
• Drag Country onto the Color Mark.
• Drag Path (bin) onto Columns.
• Right-click on the object, ensure that Show Missing Values is checked.
• Drag this object onto th Path Mark.
• Drag Size on Size Mark.
• Right-click on the object, go to Compute Using and select Path (bin).
• Adjust the Size to 75%.
• Drag TC_Percentage of Sales onto Tooltip.
• Right-click on the object, go to Compute Using and select Path (bin).
• Drag X onto Columns.
• Right-click on the object, go to Compute Using and select Path (bin).
• Drag Y onto Rows.
• Right-click on the object, go to Compute Using and select Path (bin).

If all goes well you should see something like the following:

Now, you have to admit, this looks pretty cool, but we are now going to update the Table Calculations for X and Y.

• Right-click on X and click on Edit Table Calculation
• With Nested Calculations set to TC_Rank.
• Set Compute Using to Specified Dimensions.
• Ensure that only Country is checked.
• Right-click on Y and click on Edit Table Calculation…
• With Nested Calculations set to TC_Rank.
• Set Compute Using to Specified Dimensions.
• Ensure that only Country is checked.

If all goes well, you should see the following:

And now we need to adjust the cosmetics by:

• Remove the Grid and Zero Lines.
• Adjust the Distance from Center parameter.

You should now see the following:

and boom, we are done… nice and simple and a small adjustment from the previous tutorial on drawing Satellite Charts in Tableau. And like the previous tutorial, let us have some fun with some variations.

## Orbit Chart / Variable 1

Change the Mark Type to Circle.

Also try changing the Mark Type to Shape and exploring what can be done, literally, load an image of a comet and see what it looks like, or potentially a planet. Now that I think about it, set the background as transparent and have an image of the Sun in the background.

## Orbit Chart / Variation 2

Take the original and change Size to `IF [Index]<(360*[TC_Percentage of Sales])+1 THEN 1 ELSE 0 END` for the following:

are we having fun yet? This is a variation of a Radial Chart Chart.

## Orbit Chart / Variation 3

For our final variation, take the original data visualisation and change:

X

``SIN(RADIANS([Index]*[TC_Percentage of Sales]))*([Distance from Center]+[TC_Rank])``

Y

``COS(RADIANS([Index]*[TC_Percentage of Sales]))*([Distance from Center]+[TC_Rank])``

Size

``IF [Index] = 360 THEN 1 ELSE 0 END``

You should now see the following:

I was going to write a blog on Radial Lollipop Charts, so here you go.

1. Great tutorial Toan.
I have two questions, the measures used have to be always expressed as percentage?
When playing with different resolutions, just wondering, is there a way to adapt the circles to the screen size.?
Sometimes we had experience problems with mark types circles or squares that doesn’t adapt well like bar charts for instance.

• Hi Oscar, you do need the percentage to ensure that you fit within a single orbit, but you can display values via the tooltips. You will have to develop your dashboards for the target screen resolution, Tableau does have device layouts, but I don’t think it has resolution layouts, so you will have to see what is most common and work with that I am afraid. Kind Regards, Toan

2. That’s awesome, Toan.
I have a question: how can I add multiple points on the same orbit? Let’s I want to have two ‘UK’ points on the outer circle. I can’t seem to find the way to enable it.
Thanks!

3. I think you did a great job. Thanks for Sharing
but . I have one question to ask. How i develop this type of complex calculation habit,
because I am following your tutorial and calculation you used in that is not so simple, i mean its tricky.
Any suggestion

• Hi Amit, the main thing is not just to use the tutorial, but to try to understand the calculations and logic involved. Once you have done this, try to experiment and build your own data visualisations.
