<p>PURPOSE:To widely shorten time for extracting detailed information by grouping the detailed information of a data included in display range in the order of a display coordinate. CONSTITUTION:The information of a file 11 is read out and set to a buffer 12, and pictures are displayed based on the information of the buffer 12. When an operator exerts any operation such as data addition, deletion and coordinate transformation or the like upon those pictures, a sort processing 15 is executed corresponding to the respective operations. Thus, the data can be arranged in the order of the display coordinate. Therefore, the time for retrieval can be widely shortened by totally displaying the relative data on a display screen.</p> |
