Building a Tadpole Chart

Opening the Superstore Dataset

   Move Sub-category to Rows
   Move Order(Date) to Filters
and choose 2018 and 2019 only
   Move Sales to Columns
Next we will create a calculated field:
   Calculated Field:Sales(Circle)
   IF DATEPART('year', [Order Date]) = 2018 then [Sales] END
   Drag Sales(Circle) to Columns, choose "Dual Axis" and then synchronize
   On the Sales Marks Card, select Line. Drag Order(Date) to Path, select Year
   On the Sales(Circles) Marks Card, choose Circle

Format color as preferred and you should now have a Tadpole chart that looks like this:

Note: Make sure Sales(Circle) is to the right of Sales to bring circle on top of line.
