    Dealing with null values on a dual axis map

    Matthew Lynch

      Hello Everyone,


      I'm dealing with a dual-axis map. My first set of marks is a choropleth map showing deforestation rates. My second set of marks are circles representing the presence of "sustainably certified" forests.


      I would like to eliminate all null values from my second set of marks, but when I try and filter these out, data from my first set of marks is also excluded from the visualization. Is there any way to decouple these data so that I can apply separate filters (i.e. show only values >0 for my second set of marks)? Alternatively, if I could just set zero values to "invisible" for my second set of marks, this would work too (I have a feeling this isn't possible).


      Thanks you in advance!
