Method for displaying bar graph without totaling data and program storage medium thereof

摘要

There is provided a bar graph displaying method as well as a program storage medium of the method capable of easily displaying a bar graph in which each of bar portions is divided into two regions without requiring a user to perform calculation of totaling a large amount of data. A set of elements having a name attribute, a residence attribute and an age attribute is classified into subsets having no common elements by the residence attribute. Each of the subsets is divided into two regions on the basis of a threshold value of the age attribute, and the bar graph in which the bar portions corresponding to the subsets are each divided is displayed. The threshold value is displayed by the position of a bar arranged on a slider in which a setting range and a unit of the above threshold value are shown. If the bar on the slider is slid to vary the threshold value, then the subsets are each redivided on the basis of the varied threshold value, and the bar graph of the redivided subsets is redisplayed.
