I am trying to symbolize a feature service on two different fields in a Portal web map. The first field I choose I have all fields available. Unfortunately, the second field I try to choose only appears to be numeric values (field list is filtered outside my control) and I want the second field to be a string field, so I am unable to symbolize the layer like I can in ArcMap or Pro.
Has anyone ever encountered this limitation?
Any ideas on how to overcome this problem if I do not have Ownership of the data and I am required to use the data as is?
That looks like the path I will go down and I have had some success.
I am somewhat puzzled as I am unable to get one of the unique values symbolized in AGOL even though I can see the unique value symbology in Pro with the same feature service. Are there any limitations on the values that are recognized in an Arcade expression?
A lot of the symbology options will be less refined than in desktop. I'm not sure what you mean in your last sentence, but I don't think the issue is with any arcade expression, more the rendering options available.
For example, only 200 unique values can be categorised in AGOL (both in classic and map viewer) with only 10 colours available. Style categories (Map Viewer Classic)—ArcGIS Online Help | Documentation
