PROBLEM TO BE SOLVED: To graph and display statistical data through easy operation without the need to perform troublesome operation other than the input of the statistical data to be graphed. SOLUTION: When a user inputs the statistical data to be graphed by operating a data input key, the inputted statistical data are stored in a graph data storage area 14h in a RAM and then converted and reconstituted into statistical data which are allocated in 10 stages to ranges at constant intervals between the maximum and minimum values of (x) data, so that the data are stored in a converted graph data storage area 14i. Further, the maximum and minimum values of (x) and (y) data of the converted and reconstituted statistical data are detected and set as graph display ranges in respective registers xmin and xmax, and ymin and ymax in the RAM. According to a graph scale based upon the set display ranges, the said reconstituted statistical data are drawn in a graph storage area and displayed at a liquid crystal display part 16. |
