I have xcoord ycoord and state name in my database, How I can make a map chart in Metabase? And how I convert xcoord ycoord to longitude and latitude?
Looks like your xcoord=latitude and ycoord=longitude. So just make sure they are numeric, float/decimal columns in your database and change the Field Type in Admin > Data Model > (db) > (table).
Your state has to be the two letter code if you are using the built-in US States region map.
