<p>PURPOSE:To display the correlation of plural pieces of information on a CRT by real time information in an on-line operation by providing three or more unidirectional coordinate axes having the same origin in a circular graphic. CONSTITUTION:The three or more unidirectional coordinate axes having the same origin in one circular graphic are provided on a CRT screen. And one piece of process information is inputted to a computer 3 via a process input/ output device 2, and an input processing started up cyclically by a timer 4 is performed 5, and it is accumulated in a process data file 7 after being converted by a data processing 6. Meanwhile, information is indexed from the process data file 7 by a CRT display edit processing 8 started up cyclically by the timer 4, and it is converted to output information such as a numeric value, a parameter, and a trend graph, etc., by a numeric value edit processing 9 based on control information 15 for displaying numeric value, and is displayed on the CRT 12 via a CRT output processing 11. In such a way, since the plural pieces of information can be expressed on one circular graph as a correlation diagram, it is possible to express a various kinds of balance management such as distribution balance management, power factor balance management, etc., visually.</p> |
