TREND DISPLAYING SYSTEM FOR TREND GRAPH SCREEN

摘要

PURPOSE:To grasp deviation and its changing state accurately by filling a specified color in a part which is surrounded with arbitrary two trend graphs, and displaying the result. CONSTITUTION:Four trend graphs 1 - 4 are displayed in the same frame F on a trend graph screen D. Of the graphs 1 - 4, the graph 1 shows preset values, and the graph 2 shows measured values. A specified color fills a part surrounded with the graphs 1 and 2, and the result is displayed. Such a display system can be realized with a computer system comprising a CPU for executing a display control program, a display on which the screen D is displayed and an input device such as keyboard. In this way, deviation between the graphs 1 and 2 and its changing state can be readily recognized by a pattern recognizing method.
