<p>PURPOSE:To improve the efficiency of plant monitoring operation by letting an operator recognize the variation of process data clearly from the density or color variation of a graph without any error. CONSTITUTION:An output control part 12 generates display data for painting out display area of the graph frame information of a bar graph inputted from a process state decision control part 10 in respective display colors with display density corresponding to display information inputted from a process state display color control part 11, and composes and outputs display data of the graphic display data and display data on a time-base scale to a CRT display device 2. Therefore, the operator can recognize the variation of the process data clearly from the density or color variation of the graph without any error. Consequently, the efficiency of the plant monitoring operation is improved.</p> |
