Getting a little bit tricky this week, mostly because I won’t be at TC this year….. 🙁

This week we are going to do some radial mapping in Tableau. While extensions might replace this trick, I think it’s still useful when analyzing locations within N miles of a target location.

  • This is a tricky one, so the first thing you want to do is get all the Lats/Longs for City/State from SuperStore and create a new dataset with it. You need to be able to use the Lats/Longs in calcs, and we can’t use generated lat/longs at the moment.
  • Create a Parameter for City/State
  • Create a Parameter to set the number of miles
  • Create a Map of Sales for City/State sized by Sales
  • Draw a Radial Circle around the selected location that has a radius equal to the Miles Parameter.
  • The Map should be filtered down to only show locations within the Radial Circle
  • This does require some data modelling…if you get stuck, check out my blog post on radial mapping.


This week uses the superstore dataset for Tableau 2018.1.  You can get it here at


After you finish your workout, share on Twitter using the hashtag #WorkoutWednesday and tag @AnnUJackson, @LukeStanke, and @RodyZakovich.  (Tag @VizWizBI too – he would REALLY love to see your work!)
