I'm hoping to create a map with Zip Codes color coded based on a value in my data set. When I connect to my Excel spreadsheet, Tableau recognizes the Zip Codes and plots them on a map as dots. But on the options card, the Zip Code boundaries and labels options are greyed out. I've attached a screen shot to show it.
The setting is grayed out because you are zoomed too far out. But the feature you are looking for isn't available until Tableau 7.
