Azure Maps – Show Choropleth Layer and Bubble Layer Together

[PA_Sy]

Hi all,
I'm working with Azure Maps in Power BI and I'm struggling to overlay two layers in the same visual:

1. Choropleth Layer:
   I have a map showing local authorities in England (from a Geography table), coloured using a gradient based on a parameter selected by the user. The join is done via the LA Name column.

2. Bubble Layer:
   I also want to show individual properties on the map using latitude and longitude from a Property table. There are multiple properties per LA.

My Challenge:
I can get the choropleth working or the bubbles, but not both at the same time. Is there a way to show both layers in a single Azure Maps visual – i.e., a gradient-filled reference layer and bubbles for property locations?

Any workaround or setup tips would be greatly appreciated.

Thanks in advance!

You can try Symbol Choropleth map in TMap Visual for Power BI.

Hi @PA_Sy ,

Thank you for posting in Microsoft Community.

As of now, Power BI’s Azure Maps visual supports only one data layer at a time per visual, which is why you can see either the choropleth or the bubble layer, but not both. You can show both a gradient-filled choropleth layer and bubbles for property locations in a single Azure Maps visual in Power BI, but it requires configuring the visual fields correctly, and ensuring the data granularity doesn't conflict.
To make this work within the same Azure Maps visual, you'll need to bring the data together into one model/table using Power BI data modeling techniques.

To configure an Azure Maps visual:

Place Latitude and Longitude in the Location well to generate bubbles.
Add your geography field (e.g., LA Name) to the Geography well to enable choropleth mapping.

For styling and data representation:

To apply a gradient fill (choropleth), assign your measure or parameter to the Color field under Geography.
To define bubble size, input another measure (e.g., property count or value) into the Size field under Location.

This works because Azure Maps supports dual binding, one polygon layer from Geography, and one point layer from Location.

You can show both a choropleth and point data in one Azure Maps visual by:

Using the Geography well for polygons.
Using the Location well for bubbles.
Assigning measures separately to Color (choropleth) and Size (bubbles).

Ensure LA Name values match Azure Maps standards, or load custom boundaries via GeoJSON if supported.
