Patent ID: 7705854

Claim:
A machine-implemented method of displaying a plurality of similar data sets, the method comprising: receiving into a processor a plurality of N data sets, each data set including two or more data points, each data point having 2 or more data values representing a vector having a number of dimensions; generating an occurrence count array including elements by determining an occurrence count value, M, for each array element, wherein each occurrence count value, M, is a number of times a corresponding data point occurs in the plurality of N data sets, wherein each array element corresponds to a discrete interval of data values; receiving an indicator of overlap density, said indicator identifying a degree of overlap; determining the array elements that are within the identified degree of overlap; and generating graphical data for a graphical display representing said elements in the array that are within the identified degree of overlap, wherein N is an integer greater than or equal to two and M is an integer greater than or equal to zero.
