    Suppress / hide some marks on a line

    Kurt Heisler

      This tutorial shows how to use a dual axis to highlight certain marks on a line: Highlighting Points in a Line Graph — OneNumber.

       

      The example uses a simple calculated field which you drag onto the color card for the second axis (which are circles).

       

      In a case like this, is there way to hide/suppress the marks that are not highlighted? Using this example, if I change the color of those marks to white, it creates white circles instead of gray ones. If I ask the calculated field to return Null for those marks, Tableau still requires me to assign a color to Null. I would like to suppress the marks completely.
