Examples of Creating Maps<br />

Figure 16.32 Bubble Plot of Hurricanes.jmp with Background Map<br />

Now the coordinates make geographic sense. Click Run to view the animation of the hurricane data moving<br />

over the background map. Experiment with different options <strong>and</strong> view the displays. Adjust the axes or use<br />

the zoom tool to change what part of the world you are viewing. The map adjusts as the view does. You can<br />

also right-click the graph <strong>and</strong> select Size/Scale->Size to Isometric to get the aspect ratio of your graph to be<br />

proportional again.<br />

The next example uses the Katrina Data.jmp sample data table, which contains data on hurricane Katrina<br />

such as latitude, longitude, date, wind speed, pressure, <strong>and</strong> status. Adding a background map helps you see<br />

the path the hurricane took <strong>and</strong> impact that it had on l<strong>and</strong> based on size <strong>and</strong> strength. A script has been<br />

developed for this example <strong>and</strong> is part of the data table.<br />

1. Open the Katrina Data.jmp sample data table (C:\Program Files\<strong>SAS</strong>\JMP\\Samples\Data).<br />

2. Select Graph > Bubble Plot.<br />

3. Drag <strong>and</strong> drop LAT onto the Y axis.<br />

4. Drag <strong>and</strong> drop LON onto the X axis.<br />

5. Drag <strong>and</strong> drop Date onto Time.<br />

6. Drag <strong>and</strong> drop WIND onto Sizes.<br />

7. Drag <strong>and</strong> drop Stat onto Coloring.
