<p>PURPOSE:To easily enable estimation of a cause and capturing a phenomenon, etc., by displaying a plant state three-dimensionally by means of an event axis provided along a direction that an event transits, a time axis and a plant quantity of state axis. CONSTITUTION:First an individual figure display unit 4a takes a quantity of state axis as a vertical axis and a time axis as a horizontal axis to display a transitional change of a plant quantity of state measured at a position of a plant in a general two-dimensional graph 11. An event transition figure display unit 4b adds an event axis to the individual figure wherein the horizontal axis is time, the vertical axis is the quantity of state and the event axis is made in a depth direction to display a figure (event transition figure) 21 which three-dimensionally indicates a plurality of quantities of state according to a propagation direction of a disturbance along the event axis. Further, a configuration figure display unit 4c displays on a plant configuration figure 31 which parts of the plant to be measured are indicated by the plurality of graphs displayed on the event transition figure 21 thereby supporting operation of capturing a mutual relational position of an amount of taken information within the plant. Thus estimation of the cause, grasping of the event, etc., can be easily performed.</p> |
