[. . . ] You could create a bar chart map showing male and female literacy rates by country. 47 48 Chapter 8 Figure 8-1 Create Bar Chart Map: Assign Variables tab Bar Height. Leave this target blank to get the count of cases in each geographic region. You can select a summary function from the Bars Represent drop-down list. Variables with a small number of categories, such as gender, work best. If you select a bar category variable, you can select only one bar height variable. Sets the height of the bar that represents the largest data value. 49 Bar Chart Maps Sample Output Figure 8-2 Bar chart map Gross Domestic Product Infant Mortality To Create Bars for Counts of a Categorical Variable From the menus choose: Graphs Map Bar. . . Or you can select an alternative data binding method: Use X/Y Binding or Use Point Reference Table. Click the Advanced tab to select options, such as geoset layer, mismatch handling, and a variable to refine the geographic match. 50 Chapter 8 To Create Bars of Summary Statistics for One or More Scale Variables Drag one or more scale variables to Bar Height. Select a data binding method (such as Use Geographic Variables), a geoset, and other optional settings as appropriate. To Create Bars of Summary Statistics for a Scale Variable within Categories Drag a single scale variable to Bar Height. Select a data binding method (such as Use Geographic Variables), a geoset, and other optional settings as appropriate. Chapter 9 Pie Chart Maps Pie charts show the contribution of parts to a whole. Putting pies on a map enables you to see how the distribution of categories differs by geographic region. A pie chart map summarizes categories defined by a single variable, such as the political party of registered voters. The size of each slice represents either counts of a categorical variable or the summary function of a scale variable within categories of a categorical variable. Example. You could use pie charts to display the types of computer operating systems your customers are using in each region. 51 52 Chapter 9 Figure 9-1 Create Pie Chart Map: Assign Variables tab Slice By. Determines the size of each slice by the summary function of a scale variable. You can select a summary function from the Pies Represent drop-down list. Select Chart size based on sum of data to graduate pies, indicating the sum of the values represented for each pie. Pies are sized in proportion to the total value of their slices so that you can compare the distribution of values across regions as well as within a region. 53 Pie Chart Maps Sample Output Figure 9-2 Pie chart map Customer Satisfaction 12 6 1. 2 High Low Medium To Create a Pie Chart Map From the menus choose: Graphs Map Pie. . . Optionally, you can drag a scale variable to Slice Summary to create a pie in which each slice represents the value of a summary function for the scale variable for that category. 54 Chapter 9 Drag a geographic variable to Geographic Variable. Or you can select an alternative data binding method: Use X/Y Binding or Use Point Reference Table. Click the Advanced tab to select options, such as geoset layer, mismatch handling, and a variable to refine the geographic match. Chapter 10 Multiple Theme Maps You can create a map with multiple chart types, or "themes. " For example, if you want to show sales revenue and distribution cost per customer region, you could use ranges of values to show revenue and bar charts to show distribution costs. The bar charts would be displayed on top of the shaded ranges, but each theme would have a separate legend. [. . . ] · Because the data contain only one record per country, the MEAN summary function yields that value for each country. Because the same scale is used for both variables, the bar heights allow you to compare relative female and male literacy rates within each country. If it were YES, then both female and male literacy rates would be relative to that in other countries but independent of each other. PIEMAP Subcommand VAR(v1) BY VAR(v2) V1 is the variable to be summarized within each pie; you can use $COUNT instead of VAR(v1). V2 can be numeric or string and should have no more than 10 distinct values. [. . . ]
