Abstract: A method and apparatus for simultaneously displaying a plurality of time variables indicative of the condition of a dynamic system. The system is constructed and arranged to be coupled to an array of sensors each positioned for sensing a discreet signal functionally related to one of the variables and includes an acquisition module coupled to the sensors for generating time variable signals indicative of the variables, a sorter for sorting the data into rows, and a processor receiving the rows of data and for computing a function for each variable, and means for determining a color coded plot value for each computed function.
