Custom map - Show region name when hovering on a region with no results

Hello

I have created a custom map and this works as expected. However there is one thing that I don’t get to work: when hovering on a region for which there are no results (the grey areas in the screenshot below), I want the name of the region to appear. Does anybody know how to do this?

Thanks

Hi @koen
You would have to include all regions and give them a value of zero (0), and then you would join that with your normal query, which returns a value of the regions that exists in your query.

Hi @flamber, thank you for your response. I thought I had already tried what you describe. But I just retried and it works, so apparently not. Thank you very much for your help.
