ABSTRACT:
This invention relates to a system for accessing, manipulating and displaying time series from a stored collection of time series. In particular, the system permits the user to reconfigure the collection of time series by storing and separately indexing either individual time series which are generated as a result of user instigated manipulation or blocks of time series generated and/or selected by the user and for separately indexing the time series so stored so as to facilitate their accessing by the user. An index is also provided for the collection of time series which is preferably arranged in a hierarchical multilevel menu form by subject matter. This permits the user to quickly and easily locate either single time series or blocks of time series of interest. The math functions which may be performed on time series include certain moving transformations not heretofore available including moving variance, moving standard deviation and moving correlation and covariance on two or more time series. The performance of standard conversions is also facilitated by storing conversion data in the shell operating system so that such conversions can be performed in response to a simple command. The time series, both time series from the original collection and user generated time series, are graphically displayed and certain features are provided for enhancing the usefulness of such displays.
