Times associated with some of the data (300) indicated using an input device (425) on a graph showing the distribution of some items of the data are divided into a plurality of groups on the basis of the gaps between the times; data relating to desired items included in the time ranges specified for each of the plurality of groups is searched in a storage device (450); and on the basis of the search results, time waveforms (310, 320, 330) for the data relating to the desired items are prepared for each group. This makes it possible to easily grasp the form over time of the data for the items or other items within the times around the occurrence of the part of the data included in the aggregation of data related to the items. |
