Abstract
A method of controlling a process using a programmed digital computer with a set of process control programs. An operator control program allows the user to select and run a specified process and to collect measurement data while the selected process is run. A data analysis program enables interactive computer controlled data analysis, including displaying a trand chart depicting a sequence of data points, each data point representing at least a portion of the measurement data collected and stored while running a selected process. A selectably positionable pointer is displayed on the trend chart for pointing at an individual data point so that the user can select and perform a predefined task on the measurement data stored in the data structure corresponding to the data point being pointed at by said selectably positionable pointer.
