A system, method and computer program screen system comprising process monitoring displays showing complex information in condensed form; the process monitoring displays comprises part-plant displays showing an overview covering selected areas of a process plant, said part-plant displays comprising diagrams with graphs over measured parameters where the diagram's scale may be changed in order to let an operator more easily observe trends in values of the measured parameters. Combined with the diagrams are one or more visual representations showing whether one or more areas of the graph has been scaled, the said visual representation of scaling indicates the range and place of the displayed ordinates relative to a larger, preset range.
