Lasso Feature - Freeform Lasso & Data Models run on selected Data Points

Hi CD01,

long time no answer but I would like to provide you a short response if this topic is still open.

1. Freeform Lasso Selection: Unfortunately, Power BI's native map visuals only support rectangle/box select, not freeform lasso. However, you have options:

• Mapbox Visual (custom visual from AppSource) supports polygon/lasso selection
• ArcGIS Maps for Power BI also offers more advanced selection tools
• Both allow drawing custom shapes to select data points

2. Running Data Models on Selected Points: Yes! Once you select stores on the map (rectangle, lasso, or click), those selections act as cross-filters that automatically filter other visuals on the same report page. This happens natively in Power BI - your other charts/tables will update to show only data for the selected stores.

Important notes:

• Cross-filtering works within the same report page by default
• You can control interaction behavior via Format → Edit interactions
• For persistent selections across pages, consider using bookmarks or passing selections as parameters
• The selection filters your visuals, but doesn't re-run DAX measures with different logic - it just filters the context

Try the ArcGIS visual as native PBI visual for the freeform lasso capability you're looking for!

See a example how it works below:

Best regards!
