Hello,
I have a web map with feature layer connected to survey123. It has a numerical field 'cases' which provides count of HCV cases within each community polygon. I would like to show the polygons based on total cases reported so far via gradient of color. Example, polygon A has 4 survey records with cases value = 0,3,4 and 2 while polygon B has 5 cases values = 4, 1,3,2 and 2. So , total cases within polygon A = 9 while within polygon B = 12. As value of 'cases' keeps getting updating via response through survey123 and so does the total cases value within each polygon must be. For visualization, I want my symbology to dynamically get updated by showing darker color for polygon with higher number of total cases.
How can I write an arcade expression within the web map 'styles' setting to this done?
