I have been playing around with the Tableau Map functions and just noticed it was a built-in background layer displaying neighborhoods of the NYC boroughs. I got the idea of showing the YoY median percent change in rent by the Manhattan neighborhood. However, when I upload an excel file to Tableau, it doesn't recognize the neighborhoods as they are background layers. I've seen other visuals of breakdowns by the Manhattan neighborhood, so I know it's possible.
The excel file I imported contained Inward, Hudson Heights, Washington Heights & Manhattanville. Tableau is reading them as null values and won't give me the option to decide what they are.
