Example of Creating A Map in Graph Builder
The two files are implicitly linked by a Shape ID column. For example:
• The World-Name.jmp file contains the exact names and abbreviations for different countries and
regions throughout the world
• The World-XY.jmp file contains the latitude and longitude numbers for each country, by Shape ID
Note: If JMP does not recognize the names in your data, check the built-in map files for the spelling that
JMP recognizes. For example, United Kingdom is a country name, but not Great Britain.
Custom Map Files
You can create your own map files by following the same pattern as the built-in files. To add your own map
files, you need two things: a series of XY coordinates for the vertices of the polygons that describe the shape,
and a set of names for each polygon. Data and shape attributes are required to map custom shapes so you
can add your own shapes to JMP. There are two common sources for data like this: ESRI ® shapefiles and
SAS/GRAPH ® map data sets.
In order for JMP to automatically find your files, place them in the following directory:
• On Windows: C:\Users\\AppData\Local\SAS\JMP\Maps
• On Mac: /Users//Library/Application Support/JMP/Maps
Or, you can link the map files to your data files explicitly with the Map Role column property.
Note the following when creating map files:
• Each set of map files that you create must contain a -Name file and a -XY file.
• The first column in both files must be the ascending, numeric Shape ID variable. The -Name file can
contain any other columns. The shapes are built by rows. The XY coordinates have to go around the
shape rather than just define the convex hull of the shape.
• For the Map Role column property, columns that are marked with the Shape Name Definition are
searched for shape identification and must contain unique values.
• If you import an ESRI ® SHP file, it is opened in the correct format. -Name files commonly have a .dbf
extension. For more information, see “ESRI® Shapefiles” on page 416.
• SAS/GRAPH ® software includes a number of map data sets that can be used with JMP. For more
information, see “SAS/GRAPH® Map Data Sets” on page 417.
You might want to create choropleth maps of other non-geographic regions (for example, a floor of an office
building). Simply, add the two shape files for your non-geographic space. If you do not have XY
coordinates, but you do have a graphic image of the space, you can use the Custom Map Creator add-in for
JMP. With this add-in, you can trace the outlines of the space and JMP creates the -XY and -Name files for
you. You can download this add-in from the JMP File Exchange page.
