Abstract: Information processing devices each creates a dirty bit indicative of the presence or absence of update per tip in a sharing region, and updates the dirty bit in accordance with an operation on the tip. A synchronize processing section compares dirty bits of corresponding tips in a synchronous process so as to judge whether the tips have been updated in the both parties. When there is an update in the both parties, a priority side is decided in accordance with a predetermined rule, for example, such as the promoting side of the synchronous process before transmitting the entire contents of the tips.

Abstract: 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.
