Tableau is a great and easy to use data visualization tool, allowing you to create beautiful and meaningful visualizations within minutes.
From time to time I run into visualizations that are harder to implement in Tableau. Comparing two time series on a day level within the same line graph is one of them.

I’ll share the steps I’ve taken to create a similar visualization in Tableau in this blogpost.
