Abstract
An object is to provide a maintenance monitor device which can display numerical data related to three or more display items on a graph simultaneously, with high visibility and operability. A maintenance monitor device (1) is capable of displaying a graph of numerical data of three or more of a plurality of display items related to an apparatus (14) subject to maintenance on a monitor screen (10), and includes: a list display unit (2) capable of displaying a list of the display items (22) on the monitor screen; a numerical data display unit (3) capable of displaying a graph of numerical data related to the three or more display items on the monitor screen in accordance with graph axes including a first axis which includes a time axis; a position information calculation unit (7) capable of calculating position information of a cursor (28) displayed on the monitor screen; a display item recognition unit (6) capable of recognizing the display items indicated by the cursor on the basis of the position information of the cursor calculated by the position information calculation unit; and a second axis display unit (5) configured to be capable of displaying only one scale (33) corresponding to the display item recognized by the display item recognition unit on a second axis included in the graph axes.
