After bringing the data into Tableau, Chris showed Maggie the interface—everything from dimensions and measures to line graphs. He started dragging and dropping to build views, and Maggie exclaimed, “Wow, that was cool!” when charts instantly appeared.
Before long, Maggie took control of the mouse and keyboard. Chris prompted her with questions, and she’d use Tableau to answer them. When asked, “What if we want to make this chart a certain color?” Maggie promptly answered, “We drag it onto the color box.” She caught on quickly, and even discovered an insight about her favorite movie: The Lion King has the highest IMDb rating and box office sales of her favorite films.
As the viz came together, an amazing thing happened: “When we pulled in the weekly box office gross, Maggie said something didn’t look right. The running sum was backwards from the one in my Deadpool viz.” Chris taught Maggie what a running sum was, and showed her how to add a table calculation to correct the problem. (Personally, I still find table calcs tricky, and I’ve been at Tableau for 3 years, so I’m impressed!)
