My first extension: Pile
As in introduction to the beautiful world of Tableau extensions, I got to develop my very first own extension. What would it have to be? I got complete freedom to come up with something. Here’s what I did.
I’ve always been very interested in visuals. From my experience with creating iOS games to working at my first Internship at a solar company I’ve always enjoyed coding graphics. I thought it’d be fun to do something with that in Tableau. Have you ever heard someone say: “If you lay all of that next to each other, it would stretch to to moon and back 3 times!”, or “If you stack all that on top of each other, it would reach the height of Mount Everest!”. How fun would it be to be able to truly visualise this in Tableau? The idea was to be able to visualise your companies profits for example, as a pile of money next to real world object.
The result is a Tableau extension that I called “Pile”. The user places the extension on the dashboard, together with another sheet that displays company sales or profit measures and connects the two. After this, the user has various options to alter the comparison between the money and real world objects. The user can choose different real world objects and different bill sizes such as $1 and $50 bills or a €1 coin. The metrics from the selected marks in the dashboard will be summed up and the height of a real world pile will be calculated according to the actual thickness of dollar bills or euro coins. Then, the on-screen scale of the pile of money and the object such as a red telephone box will be calculated and displayed accordingly to give the user an idea of the scale. Image 1: Comparison of a pile of money next to a telephone box. Image 2: How far would a line of $1 bills stretch when you’re trying to reach the moon? I invite you to check out the extension yourself and play around with it. I hope you’ll enjoy!
