define a region from map

sudip midya Feb 10, 2019 10:37 PM

Hi,

I have a database containing lat lon of events happening in europe. Now, I can plot those in Tableau. I can select a region contour(radial selection, lasso selection etc). Now, can I save this region and label it? The reason I need it because, I need to define this region, so that I can do aggregation of any event(with lat, lon) happening in this region. It may not be in the current dataset only, the event can be happening tomorrow or sometime after? I am working on Tableau 10.2, I doubt if Tableau has any feature like this, can anybody please correct me if I am wrong.

Thanks,

Sudip

Hi,
I am sorry, the data is propitiatory, however I feel the superstore data provides lat lon, that can be used as reference. But I think the question is quite clear, please do let me know if now.

Thanks,
Sudip

Select and create a set . You can define it and use it in aggregation of any event.

Thanks for your reply. I don't think creation of set is a good idea for this, as it only creates a set of the events present at that instance rather than in that area. Actually, what I have is lat/lon of cities and lat/lon of events, now I want the map the events as when it happens to a region nearby the city, say 2 km radius. Next will follow aggregation on the same.
