2021 W38 | Tableau: How Can You Quickly Tell the Net Change Between Two Dates? (Community Challenge)


This week’s challenge is by Will Perkins

About Will: Will has been actively involved with the external Tableau Community over the past 3 years. He has spoken at Tableau Fringe Fests, multiple TUGs, and mentored various individuals in one-off questions or more long term instances. At work, he has helped build an internal global Tableau Community within JPMorgan Chase by helping setup and lead internal TUGs, deliver global training sessions, and champion the voice of the developer. He currently manages a large, global team of data visualization developers.

Personally, Will has married with his best friend for 11 years, has a happy 3 year-old toddler boy, and a new baby boy. He’s a fan of traveling, speaks Portuguese (mostly) fluently, and, if you follow him on Twitter then you know, he loves the Reface app.


About the Challenge: My inspiration comes from Google’s stock tracking. I love the simplicity of KPIs and trends with the visual of you’re doing better or worse here. Plus I love to use reference lines in multiple different ways.


  • Dashboard opens comparing yesterday’s sales to 14 days prior
