Further, steps P40 to P
As described in 43, each extracted record stored in the auxiliary file 2 is designated, converted into display coordinates based on the X-axis item and the Y-axis item of the first graphed coordinates, and returned on the first graph. Is changed to a yellow plot display as indicated by a circle in FIG.

As described above, in the computer system 20 of the second embodiment, the narrowing conditions (the narrowing items and the data) are displayed on the graph display screen created and displayed by plotting the record data in the target record file. By simply inputting a range or the like, record data that matches the narrowing-down condition is extracted and identified and displayed on the graph display screen, so that records can be easily narrowed down on the graph display screen.

In the example shown in FIG. 11 of the second embodiment, the case where the narrowing down is performed once is shown. However, the narrowing down processing may be performed multiple times by changing the condition contents. It is possible, and in this case, it is preferable to change the plot color for each narrowing-down condition and display the identification.

In this case, the display range can be specified on the graph of the second graphed coordinates, and further, the graphing and the display range can be specified in the third, fourth and plural stages. Alternatively, records may be sequentially narrowed down only by a display range designation operation. The display range may not be specified, and the records to be extracted may be narrowed down from the position of the graphed data at the display position directly specified on the graph display screen.

Further, in the computer system 20 according to the second embodiment, while displaying the second graph,
The user can return to the original first graph simply by inputting a simple instruction of "return", and also specify the display range on the second graph before returning to the first graph. When one graph is displayed, record data that matches the display range on the second graph is displayed with the plot color changed on the first graph, making it easy to narrow down the graph display for analysis. By performing a simple operation, the display can be returned to the original graph so that the relationship of the extracted record data on the original graph can be grasped.

Therefore, by utilizing the record extraction function mounted on the computer system 20 of the second embodiment, it is possible to easily extract necessary record data on the graph display screen, A record can easily generate and display a graph of a new item, and various analysis procedures based on record data can be facilitated on a graph display screen.

As a result, it is possible to easily perform a multidimensional analysis of the record data by a simple input operation on the graph.

For each of the doubly extracted data, the data is When the data is displayed on the first graph, the data is distinguished from other data in the first graph. Therefore, when narrowing down desired data from a large number of data, each data is referred to from various viewpoints. (Coordinate axes), the multiplexing can be narrowed down sequentially, and by knowing where the multiplexed data is distributed on the original graph, multiple data can be narrowed down. It can be analyzed data from various viewpoints.
