ABSTRACT:
The Swinging Door Method of compressing an industrial process data stream is described. Data used for generating a line graph is compressed for display or storage while preserving maximum, and minimum values, and other valuable data features. The method establishes offsets from a first point which then defines a corridor opening. Subsequent points are received to refine the defined error band or corridor direction until a point is received that cannot be included in the corridor. An end point for the corridor is then generated. The corridor end points then replace the intervening raw data as the output.
