Systems and methods that generate or provide overlap displays of multiple sets of data in a manner that advantageously simplifies trend visualization in large sets of data. A two-dimensional, three-dimensional, or greater-dimensional occurrence count array is generated for a plurality of similar data sets. Each element in the array is a number of times a corresponding vector of data values occurs in the plurality of N data sets, wherein each array element corresponds to a discrete interval of data values. Once the array has been generated, a graphical display of overlap density may be generated by comparing a desired degree of overlap with the value of each array element. Those array elements having values that satisfy the desired degree of overlap are rendered, as a display object, using one or more colors, shades and/or patterns representing varying degrees of overlap. |
