2. Description of the Related Art Generally, in monitoring control and facility management of facilities in which measuring equipment is arranged on a network system such as a power distribution system, an operator has a wide range of measurement data and monitoring data of a target system facility. It is necessary to grasp the detailed situation at all times and make an appropriate judgment immediately. However, in general, a screen display device equipped with a CRT or the like has a limited display area. Therefore, an overall trend graph display showing an overview of the entire period being collected and saved and a partial period showing in detail an arbitrary specific period are shown. A method such as switching between the trend graph display and the screen display on one screen display device or displaying the screen separately on a plurality of screen display devices is adopted.

In these methods, for example, first, an overall trend graph is displayed on the entire screen, and the cutout range displayed on the overall trend graph is displayed from this screen by an input designating device such as a mouse or a pen. By moving or changing the range, a cutting range to be cut out from the entire trend graph is determined, and this cutting range is displayed on the entire screen as a partial trend graph. In this method, in order to make it easier to use the partial trend graph, while the partial trend graph is displayed on the entire screen, the range currently displayed as the partial trend graph in the overall trend graph is scrolled to another range. Methods such as increasing or decreasing the range currently displayed as a partial trend graph in the overall trend graph are used.

However, in the above method, for example,
When moving the range currently displayed as the partial trend graph in the overall trend graph to another target range, the situation around the partial trend graph currently displayed cannot be seen, so scroll repeatedly. Move the range currently displayed to the target range, or return to the overall trend graph and specify the cutout range again as a partial trend graph, and then display the specified cutout range as a partial trend graph. There must be. Also, for example, even if you try to find abnormal data in the overall trend graph, it is difficult to find it unless you trace the order in the past from the latest data, because you are not grasping the whole situation, and it is difficult to find it until you find the abnormal data part. However, there was a problem that it was not easy to use because it was necessary to display a partial trend graph.

Therefore, in order to solve this problem, the inventors of the present application have invented the technique described in Japanese Patent Laid-Open No. 8-115438. In this technology, a part of the entire screen is used as a sub screen and the entire view is displayed on the screen, while the remaining screen is used as a main screen and a partial trend graph is displayed there. When changing the display range, the main screen and the sub screen are always linked to improve the operability of the trend graph display with a wide range.

[0006]

As described above, in the technique disclosed in Japanese Patent Application Laid-Open No. 8-115438, the partial view and the entire view are displayed in one screen, so scrolling or enlarging / reducing. Has greatly improved the operability of displaying the desired partial view. However, there was no particular description regarding trend graphs such as the actual trend graph. Trends such as cases where operators need to quickly grasp the time / status (frequency / trend) of abnormal data, as typified by measurement data equipment monitoring on distribution systems, gas piping systems, and network systems. It is desired to improve usability for displaying graphs.

[0007] Therefore, an object of the present invention is to provide a trend graph display device which can improve usability more than ever before.

According to the present invention, the operator can view the partial trend graph of a wide range of measuring instrument performance data as well as the entire trend graph, so that the partial trend graph in the overall trend graph is displayed. The position and the like can be easily grasped, and the partial trend graph can be easily scrolled. Also, when the partial trend graph is displayed on the main screen and the entire trend graph is displayed on the sub screen, the scroll instruction for the partial trend graph is It can also be applied to the cutout range, and the processing performed on the partial trend graph in the main screen is reflected in the cutout range in the sub screen, and conversely, it is performed in the cutout range in the sub screen. It is also possible to reflect this processing on the partial trend graph in the main screen. Further, a plurality of partial trend graphs in group units can be stored by a simple operation and can be called by a simple operation. Moreover, a part of an arbitrary partial trend graph can be cut out by a simple operation, and can be pasted at an arbitrary position on the screen to be divided and displayed.

In the above description, the trend graph displayed on the sub-screen is fixed to the entire data possession, but in conjunction with the part of the main screen, for example, the relationship between the part and the "whole period" is shown. It is also possible to variably adjust week order and year order, day order and month order, hour order and several days order, minute order and day order, and so on.
