How to force ArcGIS Pro to exactly overlay 2 label classes within one feature class?

JakubWabinski

Hello,

I suppose the question posted is rather counter-intuitive but yeah... I need it.

I wanted to ask, whether it's possible, using automatic label placement (e.g. Maplex), to force ArcGIS to generate two labels for one feature (based on 2 different attributes) in the very same place - also with proper alignment. For example, I have a city and I want to put label of its name and population in the very same place.

This might sound weird but is exactly what I need right now. The problem is that the engine tries to find best placement and at all cost avoid the contact. 

I tried converting one of the label classes to annotation but since the two classes have different sizes, the placement is always different. I tried all (I think) options within Labelling section with no success.

I would like to avoid manual placement of labels. I am attaching the screenshots to show what I want to achieve. Hope this is clear 🙂 

Take care!

Option 1:

You can achieve this using a Composite callout label style along with the PART text formatting tags along with other formatting tags to control properties such as color and font. Here's an example: 

Create a single label class with multiple fields that uses the PART tag to define where each field is placed. Add position and v_align attributes to the PART tags.

The example arcade expression below defines a PART for the POPULATION field that is in the top position, vertically aligned (v_align) to the top. It's also wrapped in a CLR tag to change that part to magenta.

Then it adds another PART for the NAME field that is in the middle position, vertically aligned to the bottom.

 

 

"<PART position='top' v_align='top'>" + 
"<CLR magenta='100'>" + $feature.POPULATION + "</CLR></PART>" +
"<PART position='middle' v_align='bottom'>" +
$feature.NAME + "</PART>"

 

 

The styles of this Composite callout use no fill no stroke and 0 margins to effectively remove the callout while utilizing the other features of a composite callout label.

 

Result:

 

 

Option 2:

I just realized you could also do this with the CLR formatting tag to modify the color of 1 field's label and modify the Line spacing (leading) to make them overlap. 

Here's the label expression:

"<CLR magenta='100'>" + $feature.POPULATION + "</CLR>" + 
TextFormatting.NewLine + $feature.NAME

Here's the Line spacing setting:

And the result:
