Patent ID: 7712032

Claim:
A range manager system comprising: a range definition controller receiving a plurality of boundary values from a user and positioning each received boundary value in numerical order on a single range between a highest value and a lowest value, thereby creating sub-ranges within the single range without requiring the user to specify the boundaries of the sub-ranges, wherein the sub-ranges are non-overlapping and collectively span the single range entirely; a range label handler applying user-defined labels to the sub-ranges; and a range definition display area controller controlling, by operation of one or more computer processors, presentation of a range definition display area to the user via an output unit, the range definition display area representing a definition of the sub-ranges, the range definition display area controller presenting the sub-ranges in vertical arrangement so as to visually convey the definition of the sub-ranges, wherein the range definition display area controller comprises: a boundary indicator controller controlling presentation of one or more range boundary indicators based on the boundary values; and a boundary value location controller controlling a location of each boundary value relative to its associated boundary indicator so as to indicate to which sub-range the boundary value belongs a range redundancy handler handling redundancy in the sub-ranges based on the boundary values and the labels of the sub-ranges such that neighboring sub-ranges having a same label are presented as a single sub-range having a single label.
