How to chart ratio of sums

Question asked by cgmcgove on Jan 12, 2018

I am using a few infographic widgets in web app builder. Each graphic sums an attribute from a grid feature service in the map extent.

The four attributes are:

  • total_population
  • Phosphorous_load
  • Nitrogen_load
  • SuspendedSolids


The goal is to show the sum of pollutants versus the sum of population. We want to show that the runoff per capita is better in our more densely developed areas.


So far however I can only seem to total any one of those attributes separately and the user is left to do the division in their heads.


Anyone know how I can get the runoff per capita division of sums?
