Abstract
Various graphical displays used for visualization of control techniques in a process control system can be provided to an operator. For example, the graphical display could include an image associated with a portion of a process and icons that are associated with corresponding process variables. At least some of the icons include a symbol that represents a change of one value of the associated process variable relative to another value of the process variable. Another graphical display could include a pigeonhole display that includes visual elements associated with corresponding process variables. Selection of a visual element could present the operator with a peephole display that includes information associated with process variables associated with the selected visual element. Each visual element displays layers of information that are associated with its process variable.
