Sometimes you read something and you just want to have fun, so therefore, I decided to write a short blog to introduce the RANDOM() function in Tableau and to use this to create a Jitter Plots.

Note: The RANDOM() function is undocumented, and therefore, should be avoided for production use and only used for fun. The function returns a floating point number between 0 and 1.

## Data

http://www.tableau.com/sites/default/files/training/global_superstore.zip

## Calculations

Columns

``RANDOM()``

Rows

``RANDOM()*1``

Note: This is the joys of a function being undocumented. If the Calculated Field has the same RANDOM() formula, it returns the same random number. Therefore, in Rows, I have multiplied by 1 to ensure that Tableau generates a different random number.

## Worksheet

To start building our dashboard:

• Change the Mark Type to Circle.
• Drag Category onto Columns.
• Drag the Columns Calculated Field onto Columns.
• Right-click on the object and select Dimension.
• Drag Region to Rows.
• Drag the Rows Calculated Field onto Rows.
• Right-click on the object and select Dimension.
• Drag Category onto Color Mark.
• Drag Product Name onto the Details Mark.
• Drag Sales onto Size.
• You can choose any metric you fancy.

If all goes well, you should see the following:

Now that we have the visualisation, we will adjust the cosmetics:

• Set the Grid Lines to None.
• Set the Zero Lines to None.
• Hide Field Labels for Rows.
• Hide Field Labels for Columns.
• Rotate the Region label text.
• Edit sizes.

You will hopefully have the following.

and boom, we are done with this short and quick example. You can find my work on Tableau Public at

I am going to explore putting Jitter Plots into shapes and other data visualisations like my Sunburst or Radial Bar Charts, just for fun of course.
