Priorities for labelclass?

EricRydgren

Hi,

I am trying to prioritize my labelclasses by a custom variable. The documentation says "Defines label priorities", which should meen that you are able to prioritize the labels somehow. I cant find any property that will help me do that?

Any suggestion on how to solve my problem?

I am using ArcGis 4.11.

Thank you in advance!

Hi!

- Would supporting a LabelClass.priority property be enough to fit your use case?

Yes, i think that will do the trick. Preferebly as an integer, to get infinit number of priority-levels.

- Do you only want to pin a specific feature's label?

No, no need to prioritize specific features label.

- Do you want the priority to differ between features of a given labelClass? (make it attribute-driven)

No, for a given labelclass I only need the priority property, in my case.

Is this something you will consider implement soon?

Best regards, Eric

Hi Eric Rydgren‌,

Yes I don't think we yet have a great way of doing what you are asking for, however I have heard a request for something similar from other users in the past. Can you give us a few more details?

Thank you for your response!

Unfortunatly I think you have missunderstood the question, or maybe I was not asking it clearly enough.

What i meen is that i want to prioritize the drawing order of the labels, which means if 2 features are placed close to eachother in the map, I want to specify which of them that will be visible for the user.

Is there any way to make such prioriting for labelclasses?

Thank you!

Currently, label priorities can be established using a where expression:

https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-support-LabelClass.html#where

This allows you to only label features that evaluate to `true`. You can also create multiple label classes with different where expressions:

Sample Code | ArcGIS API for JavaScript 4.15

Down the road we are considering different methods to establish label priorities. Also, please consider upgrading to the latest version of the JS API, which is 4.15.

Hope this helps!
