Abstract:
A computer software system for displaying time series data as an image in which one axis represents sequential time and a second axis represents an offset in time from the time represented by said first axis on a display device, wherein the computer software resides on a computer which comprises at least one storage medium, at least one CPU, a power means, and an operating system, the computer software system comprising the steps of:A) reading data from archive after entering;B) computing fluctuations/first differences or standardized returns;C) computing distance from fluctuation pattern at time I to fluctuation pattern a time I-j;D) multiplying distance by scale factor;E) computing color from scaled distance so that (i) the colors with hues from red to green are assigned to values of the scaled distance greater than the median of all scaled distance values encountered in the time series, while colors with hues from green to blue or black color are assigned to values of the scaled distance smaller than the median value, and (ii) at least two readily distinguishable colors are assigned to distinguish two different intervals of scaled distance above the median;F) applying the color to column I, row j;G) determining that row j is not the last row and increasing j by one; andH) repeating steps C through F.
