I am struggling how to design a filled map on Zip code areas when my source data (list of Outlets and their sales) doesn't include the zip code but concrete outlet latitude and longitude.
Attaching a printscreen - I easily visualized individual outlets in a map, and I can color them by Sales volume (HL). Switching on ZIP code borders and ZIP code names in the map layer I can see the ZIP code the outlet is located in. But I struggle how to design a filled map coloring ZIP code areas by sum of HL of outlets in there. ZIP code attribute is not coming with the source data, just outlet latitude and longitude.
Is there any in-box function / feature in Tableau to assign a zip code based on data point lat & lon?
Thanks for advice
