Arcade Scripts with Map Service

JasonSmith6

Has anyone had lucky getting Arcade scripts to work on symbology and labels for a Map Service? I am publishing a map service from ArcMap since it supports grouping of layers, and want to add Arcade scripts to the sublayers. But when I try to create a New Expression within AGOL either under symbology or labels, it doesn't show up as an option. I can still use Arcade scripts for pop-ups, but I really need it to work symbols and labels.

Hi Xander Bakker‌,

Thank you for responding! No I own the service and published it. Is there a setting in ArcMap that I can change? The service is behind a firewall so unfortunately cannot share it.

Yes we looked at using JS 4.x which supports GroupLayer, but then it doesn't support labels natively and Arcade along with those.

Hi Jason Smith ,

I'll assume that you are not the owner of the service or that there are other reasons to not implement this while publishing the data. When you add multiple layers of a MapService you do not have access to change the symbology or define labels. The only thing you have access to is the pop-up window where Arcade can be applied. Or at least that is what I am seeing:

Can you share the service or can you share a screenshot of what option you have?

You could use code (ArcGIS API for JavaScript) for this, but I wonder if you would like to go there: GroupLayer | API Reference | ArcGIS API for JavaScript 4.6

HI xander_bakker‌, yes you're correct. When you add individual layer it works fine. But I need to keep the Grouping heirarchy (in other words, the entire map service) together. I then want to define the symbology and labels for each layer within the map service using new expressions, but can't. I was just wondering if there is a workaround using code or another means? Thanks.

Can you share the service? I just used some maps services from the sample server, like this one: PublicSafety/PublicSafetyOperationalLayers (MapServer) and when I add the individual layers, I can add new expressions to define the symbology and labels. When I add the entire map service I can configure the pop-ups of the layers using new expressions, as advertised.
