ABSTRACT:
A graph creation apparatus and method for creating graphs in the designated object scope of table data inhibits the creation of a meaningless graph, having too many items to be readable. An upper limit for the number of items for a column and for a line is determined for each graph type, whereby the designation of a number of items exceeding this upper limit is made invalid, and a warning is issued to the operator. Also, when the designated scope is displayed and updated on the table data in conjunction with the scope designation operation, updating for an invalid designation is inhibited. Prior to the designation operation, the effective designation scope is displayed. Alternatively, for the designation of a number of items exceeding the upper limit, data for a plurality of items are unified into one item, to bring the number of items within the upper limit to create a graph.
