Data Display System

A data display system comprising:

• a storage device that stores data relating to a plurality of items in association with respective times;
• a display device that displays a first graph indicating distribution of data relating to one item of the plurality of the items;
• an input device that designates a portion of data included in the distribution of the data indicated in the first graph;
• and
• a processing device that decides a plurality of time ranges for searching data of the storage device based on the time associated with the portion of the data designated by the input device, searches data included in the respective time ranges, that is, data relating to desired items among the plurality of items, from the storage device, and displays a second graph indicating temporal changes of the data based on results obtained by searching the data relating to the search results, on the display device for each of the time ranges.

A data display device comprising:

• a storage device that stores data relating to a plurality of items in association with respective times;
• a display device that displays a first graph indicating distribution of data relating to one item of the plurality of the items;
• an input device that designates a portion of data included in the distribution of the data indicated in the first graph;
• and
• a processing device that performs a first process of dividing times to be associated with the portion of data designated by the input device into a plurality of groups based on intervals of respective times, a second process of searching the data relating to desired items included in time ranges regulated by first and last times respectively included in the plurality of groups from the storage device, and a third process of displaying a second graph indicating temporal changes of the data relating to the desired items based on the search results on the display device for each of the plurality of time ranges.

A data display method comprising:

• a first step of creating a first graph indicating distribution of data relating to one item among the plurality of items, by using a storage device that stores data relating to a plurality of items in association with respective times;
• a second step of designating a portion of data included in the distribution of the data indicated in the first graph;
• a third step of dividing the times to be associated with the portion of data designated in the second step into a plurality of groups based on intervals of respective times;
• a fourth step of searching data relating to desired items included in time ranges regulated by first and last times respectively included in the plurality of groups from the storage device;
• and
• a fifth step of creating a second graph indicating temporal changes of data relating to the desired items based on the search result for each of the plurality of time ranges.
