1. A display system, comprising:
a rotary machine device that includes a rotary machine and a drive machine that causes the rotary machine to rotate;
a display device configured to display a state of the rotary machine device;
detection sensors that acquire a plurality of state quantities indicating the state of the rotary machine device;
a processor configured to set a threshold, corresponding to the respective plurality of state quantities, for detecting abnormality of the rotary machine device, in a mutually associated state; and
a display that displays a chart on the display device, on the basis of the plurality of state quantities acquired by the detection sensors, the chart being configured as a multidimensional chart in which the plurality of state quantities of the rotary machine device at specific times are plotted and the threshold at the specific time are displayed
wherein every axis of the multidimensional chart is set to a respective one of the plurality of state quantities acquired by the detection sensors.
