    Sankey Polygon "Size" Question




      I'm building a Sankey Polygon Workbook in Tableau.  I am able to recreate the workbooks that I've found on Tableau Public, but the problem I'm running into is I don't understand how some of the examples are defining "Size".  Sometimes Size is calculated, but most of the time it is already a given in the workbook.


      Here is an example where "Size" is calculated (see attached):



      In the attached Tableau workbook:  "Polygonic Decision Tree.twbx" Size is calculated.  Size is calculated using another calculation that refers to a Parameter called "Choose Size Indicator."


      Thank you!!!
