Abstract: A method is provided to display a plurality of signals, on a display screen with an intuitive graphical interface, wherein a user has ability to monitor overall data from a single view. A plurality of signals having different frequencies and remaining in a complex relationship with each other may be visualized. Each signal may be displayed by using a symbol, wherein a quasi static signal is graphically depicted using a limit symbol while the dynamic signals are visualized using bar symbols. The symbols may be arranged horizontally, on multiple image planes, in close proximity to each other. A limit symbol may be positioned on the topmost image plane in such a way that if one bar reaches the limit symbol, the bar symbol is at least partially covered. The spatial relationship among the symbols is such that the user can easily determine if an actual signal output matches planned or scheduled output or if it does not exceed the total available capacity.
