Overview of Mapping
Graph Builder
There are two types of map support in JMP: one where a map shows the data (Graph Builder) and one
where a map provides context for the data (Background Maps). You can also create your own maps.
You can interact with Graph Builder to create compelling visualizations of your data. JMP includes
graphical support to display analyses using background maps and shape files. You can add color and
geographical boundaries to maps through the following zones:
• The Map Shape zone assigns geographical boundaries to a map based on variables in the data table.
The map shape value determines the x and y axes.
Boundaries such as U.S. state names, Canadian provinces, and Japanese prefectures are installed with
JMP. You can also create your own boundaries (geographical or otherwise) and specify them as a Map
Role column property in the data table.
• The Color zone applies color based on a variable to geographical shapes.
• The Size element scales map shapes according to the size variable, minimizing distortion.
Background Maps
You can add background maps to any JMP graph through the Set Background Map window. You can use
built-in background maps or connect to a Web Map Service (WMS) to display specialty maps like satellite
images, radar images, or roadways. Right-click in a graph and select Background Map to choose from the
following images and boundaries:
• Simple Earth and Detailed Earth maps are installed with JMP.
• NASA server provides maps using a WMS to show their most up-to-date maps.
• Web Map Service lets you enter the URL for a Web site that provides maps using the WMS protocol.
You can also specify the map layer.
• Boundaries for various regions.
Example of Creating A Map in Graph Builder
This example uses the Crime.jmp sample data table, which contains data on crime rates for each US state.
1. Open the Crime.jmp sample data table (C:\Program Files\SAS\JMP\\Samples\Data).
2. Select Graph > Graph Builder.
3. Drag and drop State into the Map Shape zone.
4. Drag and drop Burglary into the Color zone.
