    Overlaying two maps: one with shapefile polygons and one with lat/long points

    Alex Sheldon

      Hi all!

       

      I hope you can help me with this one! I want to overlay two maps and the basic instructions for creating a dual axis aren't working for me. (Please excuse my lack of lingo expertise here - I only started with Tableau about a month ago!)

       

      One map joins two datasets (one is a shapefile joiner that essentially draws the census tract neighborhoods with path order and lat/long and the other is census information at the census tract level) and the other map is a series of incidents that occurs at specific geo points (using latitude and longtiude).

       

      I'm attaching screenshots of the two maps I created here. When I try to outer join the second map points lat/long to the shapefile lat/long, something goes wrong on the map and it no longer recognizes the census data. If this works, I would certainly change the color of the points in the second map so that they would show up.

       

      Any advice is welcome!
