    Help with Tree Map and Parameters?

    Ozzie Chung

      Hi, for context I'm not very good at Tableau.


      I created a tree map using EPA emissions data found online. I'm trying to create a tree map with dynamic parameters in the form of a slider of "Top 10 (Car) Models by City MPG". However, what's been frustrating me is that the number of "boxes" that make up the tree map never seems to be the same as the number I want to display on the slider.


      So, a slider of "Top (5) City MPG Leaders" would show 7 boxes, Top (6) Leaders shows 9 boxes, and so forth.


      Can someone help explain what Tableau is doing behind the scenes so I get a better understanding on this problem? Thank you.
