For most graphs that Prism creates, the structure of the data table and the location of the data within the data table determine where data end up on the graph. In contrast, Prism creates Multiple Variables graphs by assigning different variables within the data set to different aspects of the graph. Using the Format Graph: Multiple Variables dialog, you can quickly re-assign which variables are used to determine the visual properties of the graph. The following sections describe each of the components of the graph that can be customized, and how different variable assignments may affect those visual components.
