How to combine data source-based latitude and longitude with generated latitude and longitude on a dual axis map.


Tableau Desktop


    1. Create a custom geocoding .CSV file that correlates all of the latitude/longitude coordinates with the required nomenclature. For more information, see Creating an Import File.
    2. Import the custom geocoding into Tableau Desktop. For more information, see Importing Custom Geocoding.
    3. Use the name-based recognition to set up a dual axis view exclusively based on generated latitude and longitude values. 


    Tableau Desktop does not recognize that the latitude/longitude of one dimension are related to the lat/long of another dimension (such as the custom lat/long compared to generated lat/long). Therefore, when the second set of lat/long are placed on the row/column shelves, they restrict the potential points of the dual axis. In effect, any dual map information can only be plotted on the secondary map if the lat/long coordinates match the lat/long already on the view.
