Creating a Soundwave Chart in Tableau

EDIT: This post was previously named "How to make the histogram which looks like a audio wave thing (in Tableau!)" - But that seemed a bit naff. So I updated the title.
And added a viz at the bottom!

I use sports data a lot - I understand it intuitively and always have more questions I want to ask of it and find out more. So you could say I think about it fairly frequently, even if it's a subconscious thing.

Such an event occured this morning as I was walking to work from Liverpool Street station. One of the visualisations I'd created yesterday took two different line charts and filled the space in between. It was a crude solution, but it worked and it got me thinking... Remember the shot worm (see below)? Could I recreate something like that in Tableau?

This is from Peter Beshai's awesome interactive dashboard 'Buckets'

Luckily, I had a basketball dataset to hand, as one of the Makeover Monday (run by Andy Kriebel and Andy Cotgreave) challenges were on Steph Curry and his ridiculous streak.

Long story short, I did a mini-makeover of my own effort, and ended up with the below.

NB; it's very crude, I didn't update the headers or annotations or anything.. I even moved Steph across in Paint.


How was this done? Check out the short video below.

UPDATE (31/05): I actually created a visualisation which uses this technique to show how the chart could be used with NBA Statistics. Check it out below.
