Displaying and manipulating data

Diverse data sets such as microarray data and other biological data are graphically displayed and sorted to develop visual similarities, correlations or trends that can be seen by a user of software systems, methods and recordable media for organizing and manipulating such data sets to facilitate identification, trends, correlations and other useful relationships among the data. Various schemes for graphical representations of the data, as well as sorting schemes are provided, including sorting schemes performed relative to pseudo-data vectors (322, 332).
