It also has X and Y coordinates for each shape. In the XY file, you see the Shape ID, which corresponds to the Shape ID in the Name file. In the Name file, you see a Shape ID and various shape names, including the ISO code. Here, we see the Name and XY files for the world. For each territory, there are two files: a Name file and an XY file. We click Open the Sample Data Directory, navigate up two levels, and open the Maps folder. To see the shape files that are available in JMP, we navigate to this directory using Help and then Sample Data. Shape files for many regions, and the world, can be found in the JMP sample data directory. Let's talk about how this map is created. We can see, geographically, how mobile phone subscriptions have changed, globally, over time. As we scroll through the years, the colors in the geographic map update based on the mobile phone subscriptions for the selected year. Here, we select Local Data Filter under the top red triangle, and select Year as the filter variable. To see the mobile phone subscriptions for a particular year, we can use the local data filter. So, this is combined data for all of the years. This enables us to better compare the mobile phones for the different countries. We'll change the color gradient to a sequential theme and change the scale type to quantile. Now, when we drag a variable like Region or Mobile (per 100) to the Color zone, the map is colored by the values of these variables. The boundaries of each of the countries are automatically drawn, and the axes are now latitude and longitude. To create a geographic map for these data, we drag the ISO code to the Map Shape field. Because we have the names of the countries and the ISO codes, a geographic map can be created using Graph Builder under the Graph menu. The data set includes information on 217 countries grouped into seven regions and four income groups. Remember that this is data about mobile cell phone subscriptions per 100 people, from 1990 to 2017. In this video, we show how to create a geographic map using shape files and the Mobile Cellular data.
