Symbolizing the Map by Subregions
In a previous activity, you learned how to rename the data frame and change the background color. Open the data frame properties and navigate to the General tab. Change the name to “World Map.” Then, on the Frame tab, change the background color to Gray 10%. When you are ready, click OK. You may get a repeat of the coordinate system warning. Ignoring it during this activity is OK. Click Yes, to close the warning.
In the Table of Contents, right-click on the countries layer to open the attribute table. Take a moment to read through the table to find out what kind of data is available about the various countries around the world. When done, you may close the attribute table.
In the table of contents, right-click on the countries layer again to open the properties. Navigate to the symbology tab. On the left choose Categories and select Unique values. Uncheck the box next to all other values. Under the Value Field, use the drop-down menu to select SUBREGION from the list of attributes. Then, click the button that says Add All values. Right-click on the color ramp and uncheck Graphic View. Choose Dark Glazes from the list of choices. When you are ready, click OK.
Another way to change colors is to click the symbol in the table of contents. In the table of contents, click the line symbol for the graticules. When the symbol selector appears, change the color to Gray 70% and the line width to 0.25.
Your map should appear similar to the image below. The countries should be color-coded by subregions in the graticules should lie underneath.
