<p>In the machine generation of graphic charts (185), the machine/operator interface (12) is constructed to enable the operator to create new charts or recall previously created charts from storage (24A) Because of an easily-used and widely-applied selector mechanism (26, 54, 56, 58), it is not necessary to use a keyboard (20), except for the manual entry of textual information employed on the charts and numeric data that are not otherwise available for machine entry. The selector mechanism of the machine/operator interface (50) cooperates with a chart update loop (64) and employs a set of selection menus (52, 82, 86, 90, 98, 102) that are displayed, and from which the operator can choose a desired mode of operation (82) for composing the graphs, charts and their objects, for selection (200, 204, 242, 272) among a variety of chart objects (170, 171, 172, 176, 179, 180) and for selection (202, 246, 250, 270) of various descriptors of the charts and chart objects. These selection menus are presented to the operator in sequential and interdependent relationships (320, 322, 324) to enable an unskilled operator to create and modify (86) charts with considerable facility. </p> |
