Keith McCormick, Jesus Salcedo · 2017
This chapter discusses how SPSS Statistics has several procedures that allow users to create graphs like the Chart Builder, the Legacy Graphs, and the Graph-board Template Chooser. The standard graphs and charts in SPSS Statistics are complete entities, so that users need to know what they want to show in a graph before they create it. It shows the number of customers in each continent and each continent is represented by its geographical location. Furthermore, color saturation is used to represent values that correspond to the variables depicted on the map. Investigators can use maps to determine the locations of crimes, the spread of disease, fluctuations in temperature, population growth, distance traveled, where to send school buses, how to create new districts, and so on. Maps can use categorical variables, continuous variables, and combinations of categorical and continuous variables. A data key is a variable that contains the labels that correspond to the areas on a map. It is a way to tie the data to the map, so that the data can be displayed on the map correctly. It is important to make sure that the map and data key values match. Longitude and latitude coordinates can be created using freeware on the Internet from many different pieces of geographical information including addresses, zip codes, cities.
