ABSTRACT:
A method and apparatus for the integrated display of process events and trend data. The method and apparatus provide for a unified display of trend data and process events related to the control and/or monitoring of a manufacturing process. A workstation generates and displays a trend chart that represents values of one or more selected process parameters during a selected time window. The workstation also generates and displays an event table containing information describing process events that are related to the selected process parameters and that occurred during the selected time window.
