At this time a data display section 4 makes and displays a graph having a time axis to which time is assigned. A numerical data processing section 3 and a text data processing section 2 convert the data having a chronological item into graphics having display forms unique to a data group of the data. The graphs (5, 6) comprising graphics of thus converted data are made and displayed on the data display section 4, and on the graph, the time when the data was collected is plotted in accordance with the time axis of the graph. The plurality of data groups of respective data (graphic data 5, 6) having respective chronological items are displayed on one graph. COPYRIGHT: (C)2004,JPO
