I have a very specific symbology need that has me stumped I am using Arcpro and need a fitting arcade expression. I have a polygon feature class that has only two basic fields that need to be considered, Person and Count, with a person having one or more counts. Here is an example table Person | Count Tim         4 Tim         2 Kat         3 Kat         1 I want to symbolize the four polygons based on a color gradient using the sum of each persons' counts. In other words, I want all of these polygons to be colored based on the sum of his counts (4+2=6) and Kat's polygons based on her counts (3+1=4). So both of Tim's polygons are the same 'cold' color since his sum is lower and Kats are both the same 'hot' color since her sum is higher. Here's the catch: I do not want to edit this table by adding/calculating any fields, or use a new feature class to symbolize. I know I could dissolve on Person and sum the count fields in a new feature class to symbolize, but I want to use this feature class. I want to be able to change persons around (e.g. give change one of Kat's polygons to Tim) and that symbology will automatically update based on Tim and Kat's new count sums. So since I can't edit this table, or create a new one, it looks like my only option to work this out is in the symbology options. I think creating a custom expression for the graduated colors symbology option is the way to go. This requires using Arcade, and I just cannot seem to find an arcade expression that fits this need. ... View more

I am just starting to explore ArcGIS API for python Jupyter Notebooks and am looking for a method to display a map in my notebook that I can add shapefiles to that are saved locally. More specifically I am after a way to have a persistent map widget in my notebook that has layers that will update through various geoprocessing steps. I have explored the map.gis() function but it appears to only be able to map.addlayer() that exist on AGOL or an Enterprise portal. I would be great if I could pull local shapefiles in this same way. I have stumbled upon a couple other modules that look like they might accomplish this, but I wanted to ask here and see if there is an out-of-the-box solution first. ... View more
