Azure Maps selection limit (3,500 data points) – how can I count markers?

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.

Best,
