  FIG. 3 is an explanatory diagram showing an example of the long-term data display screen 22 displayed on the display device 14. As shown in FIG. 3, the long-term data display screen display means 19 expands the long-term data D1 on the time axis designated by the input device 13 when displaying the long-term data display screen 22 on the display device 14. The other long-term data D2 to Dn are reduced and displayed. In this state, when it is desired to enlarge and display the long-term data D2, the long-term data D2 is designated by the input device 13.

  As a result, the compression / enlargement display switching means 20 is activated, and the compression / enlargement display switching means 20 enlarges and displays the long-term data D2 designated by the input device 13, as shown in FIG. The period data D3 to Dn are reduced and displayed.

  In the above description, the case where the long-term data element is the supply and demand information of the interconnection system has been explained. However, it is basically effective for information having the time axis on the horizontal axis. It can also be applied to blood pressure recording tables. Thereby, it is possible to grasp information that protrudes from the overall trend of data for a long period of time, and to grasp detailed information effectively.

  In the above description, the case where long-term data is one element has been described. However, the present invention can be applied to a plurality of elements. In the case of a plurality of elements, the long-term data storage unit 15 stores long-term data for each of the plurality of elements. In this case, the long-term data display screen is configured such that long-term data for each of a plurality of elements is displayed at a time on the long-term data display screen. That is, the long-term data display screen is configured so that the long-term data of the element designated by the input device 13 is enlarged and displayed, and the other long-term data is reduced and displayed. Then, the compression / enlargement display switching means 20 performs display switching between enlarged display and reduced display of the long-term data of the element selected by the input device.

  FIG. 5 is an explanatory diagram showing an example of a long-term data display screen 22 that displays long-term data of a plurality of elements at once. FIG. 5 shows a case where long-term data Da, Db, Dc of three elements is displayed. Compared to the long-term data display screen 22 shown in FIG. 3, long-term data Db and Dc of a plurality of elements are reduced and displayed at the bottom of the long-term data display screen 22. That is, the long-term data Da of the element selected by the input device 13 is enlarged and displayed, and the long-term data Db and Dc of other elements are reduced and displayed.

  In this state, when it is desired to enlarge and display the long-term data Db, the long-term data Db is designated by the input device 13. Thereby, the compression / enlargement display switching means 20 is activated, and the compression / enlargement display switching means 20 enlarges and displays the long-term data Db designated by the input device 13.

  FIG. 6 is an explanatory diagram showing an example of the long-term data display screen 22 when the long-term data Db is enlarged and displayed while the long-term data Da is enlarged and displayed. It is selected by a command from the input device 13 whether the long-term data Da is displayed in an enlarged manner or whether the reduced data is displayed when the long-term data Db is enlarged. When the elements of two long-term data are enlarged and displayed, the long-term data of those elements can be easily compared. Since a plurality of elements (interconnection lines) can be compared and displayed, the range of use is expanded.

  FIG. 7 is a configuration diagram of Example 2 of the long-term data display system according to the embodiment of the present invention. In the second embodiment, when a long-term data threshold is set from the input device 13 in the long-term data display system shown in FIG. The long-term data display screen display means 19 displays on the long-term data display screen 22 a period in which the long-term data searched by the data search means 23 satisfies the threshold. .

  FIG. 8 is an explanatory diagram showing an example of the long-term data display screen 22 in the second embodiment. FIG. 8 shows a long-term data display screen 22 that displays long-term data of a plurality of elements at once. The long-term data display screen display means 19 displays a slider bar 24 for setting a long-term data threshold on the long-term data display screen 22. When a long-term data threshold is set by operating the slider bar 24 from the input device 13, the data search means 23 searches a period that satisfies the threshold from the long-term data Da that is displayed in an enlarged manner. For example, if the free capacity ratio (10%) of the interconnection line is set as the threshold value for the long-term data, the data search means 23 uses the expanded capacity long-term data Da to display the free capacity ratio (10 %) To search for a period of long-term data that satisfies. The long-term data display screen display means 19 uses the long-term data retrieved by the data retrieval means 23 as a mark 25 as a period when the long-term data retrieved by the data retrieval means 23 satisfies the vacancy rate (10%) of the interconnection line as a long-term data display screen 22. Display above.

  FIG. 9 is an explanatory diagram showing an example of the long-term data display screen 22 when the threshold value is changed by the slider bar 24. When the empty capacity ratio of the interconnecting line as a threshold is changed from 10% to 3% by the slider bar 24, the mark 25 indicates a period corresponding to the empty capacity ratio interlocked with the slider bar 24.

  Thereby, information with high reference frequency can be shown by filtering, and a target period can be found from long-term data. For example, in the interconnected line, the confirmation frequency of the presence or absence of the free capacity of the interconnected line is high, and only by operating the slider bar 24, there is no interconnected line with no surplus in the free capacity or in the free capacity. It becomes possible to confirm the corresponding period of the interconnection line at a glance.

  As described above, according to the embodiment of the present invention, it is possible to display all information at once for a large amount of data over a long period of time, and confirm a large amount of data configured over a wide range. Can be done without much time and effort.
