Hi @Derrell Pate
Please verify the data your using in the join condition.
Here your using the fields stormnum and Geoid10 but the data in the two fields are not having any matching data bcz of that its returning no records. Full outer join will give you the all the records in the two table irrespective of join.
Please mark this as answer if your question got resolved.
I took a different approach to the polygon rabbit hole, I've replaced the background map with an image of the hurricane. You can overlay your postcodes over the top to obtain analysis (even turning on the superstore ones is interesting ).
To do this I just googled up a few open WMS servers and added them into Tableau - unfortunately this was more miss than hit but I ended up with a current one.
