Abstract
A system to provide real-time process information to a user for a multivariable process operable under control of a plurality of process variables includes a controller operable to control one or more process variables and provide data representative of such process variables. The system further includes a graphical user interface which receives data representative of the process variables from the controller to display on a single display screen a plurality of display regions. The display regions include at least an overview trend display region to display one or more trend shape elements representative of historical data for corresponding process variables and a process variable detail display region to display a graphical representation of details associated with a selected process variable. Further, the display regions may include a matrix display region to display an array of information describing at least one characteristic associated with the one or more process variables listed in association with the array. The overview trend display of the graphical user interface includes trend shape elements representative of process trend behaviors. Each displayed trend shape element …
