Hi. In ArcGIS Online using the web map Attribute Expressions builder, I'm trying to pull feature xy coordinates to show in a popup. In the builder, my code successfully tests with a value; but the value in the popup and layer table is empty. I'm using a map service if that matters.
So, is this code supposed to work? Or am I doing something wrong?
Thanks.
This function seems to work properly.
Text(Geometry($feature).x);
and returns this in the popup
Have you checked the popup configuration to see if it's displaying the custom expression?
Thanks for the help so far. Are you using map services or feature layers/services?
Thanks.
I used a hosted feature service.
Thanks everyone for the help so far. I do see the code works with map services. The field in the table won't always populate (for me anyway) so I didn't catch that it worked in the popup.
I think the problem is with the map service I started with. I haven't figure out why, yet, but it appears that the "point" feature-type layer loaded via the map service is really a "multipoint" layer/feature class. For some reason the point-related arcade expression code works with the layer in the expression builder, but perhaps not outside of the builder. I'm looking more closely at our map service and the map viewer.
If anyone would like to take a closer look, here's the map service: NCDOT_STIP (MapServer)
Thanks again. I really appreciate the help.
For multipoint geometry you may want to try this:
return Round(Geometry($feature).points[0].X, 2)
and:
return Round(Geometry($feature).points[0].Y, 2)... since it is a collection of points although each multipoint only has a single point (as far as I could see from a query on your REST service)
Not sure what might be going wrong in your case. I just configured something similar and it works.
I entered the pop-up settings and added two expressions:
and the result is displayed:
