Abstract: A graphical user display for providing real-time process information to a user for a continuous multivariable process operable under control of a plurality of process variables which include at least manipulated variables and controlled variables includes a matrix array of information describing at least one relationship between one or more controlled variables displayed along a first axis of the array and one or more manipulated variables displayed along a second axis of the array. Further, the display includes one or more graphical devices. Each graphical device is positioned in proximity to a corresponding process variable of the controlled variables and the manipulated variables. Further, each graphical device is representative of at least a state (e.g., current value state, past value state, or predicted value state) of the corresponding process variable. A computer implemented method for providing the graphical user display is also provided.
