摘要：
Qualitative representation of signal trend is useful in various applications to model temporal evolution. Monitoring and decision support of process plant operation is one of the typical application examples. Graphical representation of two temporal signals in a two variables plane often characterizes special features of data. This paper presents an effective online method to extract qualitative representation of movements in a two variables plane. The method is applied to a diagnosis of a control valve in an industrial plant.
