Azure Maps selection limit (3,500 data points) – how can I count markers?
Hi
I'm trying to check the number of markers appearing on an Azure Maps visual in my dashboard. The markers represent rows (records) in a table, using the 'public address' field.
I've tried using the selection tool. There should be 7426 markers within my selection, but I get the message:
'You can only select up to 3,500 data points at once. Your selection has not been made.'
Is there any other way of checking the number of markers appearing, or another approach that would allow me to confirm the total?
Any advice or guidance would be really appreciated.
Best Wishes

Hi jfarj
The 3,500 point limit is a hard cap on the lasso and rectangle selection in the Azure Maps visual and cannot be raised from Power BI Desktop. That selection tool is really meant for cross-filtering other visuals, not for counting.
For the count itself, don't rely on the selection. Add a Card visual next to the map with a measure like:
Total Markers = COUNTROWS('YourTable')or DISTINCTCOUNT('YourTable'[public address]) if you want to count distinct addresses. The card lives in the same filter context as the map, so any slicer, page filter, or drill respects it, and you get the true number without the 3,500 cap.
If you need the count inside a specific region rather than the whole page, add a slicer or filter for the geography you care about (country, state, postcode range, etc.) and let the card reflect that. Counting inside a freehand lasso area is not supported today.
If this helped, please give a thumbs up and mark it as the solution.
