Use the Format Variable dialog box to format the appearance of variables in tables and the scale information in Graphs.
To open the Format Variable dialog box, right-click (Ctrl-click on the Mac) inside of the table or graph. Then, on the menu that appears, select Format. Select the name of the variable you want to format from the submenu that appears.
Note: The selections you make here for precision, units, and scaling affect the display on the graph or table only. They don't change the way the variable is presented elsewhere in the model, or the way that its value is computed.
