A range manager system has a range definition controller, a range label
handler, and a range definition indicator controller. The range
definition controller controls setting of one or more boundary values
defining one or more ranges. The range label handler handles labels of
the ranges. The range definition indicator controller controls
presentation of a range definition indicator representing definition of
the ranges. The range definition indicator controller presents the ranges
in vertical arrangement so as to provide an intuitive representation of
the definition of the ranges.
