  • Patent number: 5557716
    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.

  • Patent number: 5486055
    Abstract: An apparatus for precisely printing information at a predetermined position on a label on a sheet which has been set at an arbitrary position in a document processing apparatus includes a keyboard for inputting into the document processing apparatus data representing the relative position of print information to be printed with a print head with respect to a print start position and data representing an absolute position of the print start position with respect to a predetermined and fixed reference position on a print plane. The apparatus also includes a central processing unit for controlling the movement of a carriage supporting the print head so that the print head first moves to the absolute position input by said second input means and then moves according to the data representing the relative position of the print information during printing.
