Choose a COLUMN to be used in a visual with a slicer

PorterSmash — Tue, 24 Jan 2023 20:52:13 GMT

In short: I want to (effectively) choose the COLUMN within any given visual by using a slicer or parameter. [End]

My specific situation "in long": Let's say I have Map visual. For the location data field, I have a column that contains zip codes. I have another column in the table that tells whether that Zip code is closer to New York City, or if that Zip code is closer to Los Angeles. I have another column in the table that tells whether the Zip code is closer to New York City, or if it is closer to Dallas Texas. Like this:

Zip	NYC or LA	NYC or Dal
23158	NYC	NYC
36821	LA	DAL
18632	NYC	DAL

I want the bubble representing the zip code to change color based on which city is closest. So I can put "NYC or LA" in the Legend spot on my visual, or I can put "NYC or Dal" in that spot. But I cannot put both. I want to be able to switch between the two using a slicer or parameter. So the Zip 18632 would change color after changing the slicer. [End]

I know you can do something SIMILAR to this using measures. Specifically, the SELECTEDVALUE() function. However, I need a row by row value. Context can be applied automatically when used in the correct visual, but I need a Map.

I attempted this tutorial. But despite the title, it just doesn't work for columns.

I am open to any ideas. If it would work by using a single column "NYC or NEW" and the column could be re-evaluated based on a slicer, that would work. The data is completely open to modification.

Check if field parameters can help

This does exactly what I'm asking for. I looked at this exact thing and thought it didn't work. I have no idea how I missed it. Thank you for removing the wool from my eyes.
