Beschreibung
Zusammenfassung:	A heat map display apparatus includes a heat map display unit that displays a heat map based on a plurality of sets of data items collected from devices in a plant, each set of data items corresponding to a data series in a graph, an amount-of-change calculation unit that calculates, for each data series, amounts of time-series change in a set of data items on the basis of the sets of data items used to display the heat map, a target selection unit that selects a data series having a large amount of change in a set of data items on the basis of the calculated amounts of time-series change in the sets of data items, and a line graph display unit that displays, in association with the heat map, a line graph indicating the set of data items in the selected data series.
