Claim 7:
8. A non-transitory computer-readable storage medium having stored thereon computer-executable instructions, that when executed by a processor, cause the processor to execute operations, the operations comprising:
acquiring data indicating a plurality of sensor detection values arranged in order along a specific variable axis;
storing the data indicating the plurality of sensor detection values in a memory;
detecting a plurality of change points that are data points at which respective sensor detection values of the plurality of sensor detection values on the specific variable axis changes by at least a predetermined value in the stored data;
calculating, for a target change point that is one change point among the plurality of change points, an index value representing a degree of abnormality of the target change point using the target change point and a reference change point that is another change point among the plurality of change points, wherein
the calculation of the index value includes calculating an absolute value of a difference between a target detection value that is a sensor detection value of the plurality of sensor detection values at the target change point and a reference detection value that is the sensor detection value at the reference change point; and

controlling display of the index value and a time point on the specific variable axis at which the abnormality has occurred.
