Abstract
A graphical user display for providing real-time process information to a user for a process that is operable under control of one or more process variables is described. The graphical user display includes one or more graphical devices with each graphical device corresponding to a process variable. At least one graphical device for a corresponding process variable includes a gauge axis and at least one pair of high and low limit elements displayed on the gauge axis is representative of high and low process limit values for the corresponding process variable. A graphical shape displayed along the gauge axis is representative of the current value of the corresponding process variable relative to the process limit values. A computer implemented method for providing the at least one graphical device is also provided.
