Tableau QT: Negative Space Area Charts

Two weeks ago, I released a tutorial on a Negative Space Bar Chart, and this week, we are going to be creating a Negative Space Area Chart, and do this within 5 minutes or less.

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.

Data

We will start by loading the following data into Tableau Desktop / Tableau public.

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.

Calculated Fields

We only need to create the following Parameter and Calculation Fields:

TC_Max Sales

WINDOW_MAX(SUM([Sales]))

TC_Inverse Sales

[TC_Max Sales]-SUM([Sales])

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

Worksheet

We will now build our worksheet:

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

As you can see, we have the Sales and Inverse Sales, I wanted you to see this to enhance your understanding of what we are going to do. We will now finish off our data visualisation:

You should now have the following:

Now is the fun part:

and you should now have the following:

and boom, we are done with this Tableau Quick Tip, and I hope you had some seriously good fun; as always, you can find my data visualisation on Tableau Public at https://public.tableau.com/profile/toan.hoang#!/vizhome/NegativeSpaceAreaCharts/NegativeSpaceAreaCharts
