I am plotting data by zip codes for Seminole County in Florida. I created an Excel file with all the zip codes in one column and my data in another. When I link to MP2K, and create the map, some of the zip codes are mixed with others. For instance 32746 and 32795 data values are combined by the program, and color coded as such, and there is no boundary between them. I want to show discrete values and boundaries for each zip code. Is this possible?

Zip codes are a little tricky as they follow the pattern of the delivery routes, which are not distinct geographical boundaries.. at times they are for instance a single building or point. If you really need to do this in MapPoint, I would recommend either drawing custom boundaries or editing the zip code boundaries in a separate program like MapInfo or ArcView and then importing them using the Spatial Data Importer.
