I believe the demo used servable() to render the panel with the map. I added a print statement to the aggregator function and it did nothing when selecting different fields.
I finally changed from panel.servable() to panel.show() which popped up the panel in another tab. This did work. Confirmed by print statement added to the function. It seems like .servable option doesn’t fully work. I would like to keep it all within the notebook, but popping out to another tab is fine since I get a bigger map view.
Now I need to figure out how to filter my data points by selecting values contained in other fields. I would also like to use a box select to grab points within the box and display details in a holoviews table. Any demos or examples on how I could do that by enhancing this demo?
