Using Arc Desktop 10.3.1 and AGOnline, I have a polygon feature class showing different service zones and the dates of last service. I would like to symbolize this using a time from now, ie if it has been more than 1 month since last service date it will be yellow, if it has been more than 2 months it will be orange, etc... Is there a way to put an expression into the symbology like
if (now) - [last date] > 30 & < 60 then yellow
if (now) - [last date] < 90 & > 60 then orange
This map will ultimately be used in an ArcGIS Online web map, so it has to be dynamic and constanly updating.
