I need help aggregating areas in a predefined map in JMP 12. My data is organized by US County (FIPS) and each county is defined as being in a US region. For example, Oconee County, SC is listed as being in the "Southeast" region. I've managed to make a map of my data using a predefined map file in JMP called "Us-County-Name". This was easy to do because the JMP file has the xy coordinates of each FIPS and each of my observations have a FIPS code. Currently, the map boundaries are at the county level. I'd like to aggregate the counties into regions, the regions defined in my data set. Thanks for your help!
