1. A non-transitory malfunction analysis support program storage medium storing a malfunction analysis support program for supporting analysis of a malfunction of an object-to-be-controlled including an operational part, the malfunction analysis support program causing a computer to perform:
obtaining log data that records, in a time sequence, a state of the operational part, and input-output data of a control signal between the object-to-be-controlled and a control device that controls the object-to-be-controlled;
generating action reproduction simulation data that is a result of causing a virtual object-to-be-controlled corresponding to the object-to-be-controlled to reproduce an action based on the log data;
displaying the action reproduction simulation data on a display as three-dimensional data;
processing including at least one of displaying, on the display, a status of execution of a control program executed by the control device based on the log data, displaying, on the display, the state of the operational part and the input-output data of the control signal based on the log data using a waveform over time, or displaying, on the display, video data generated by imaging of a state of the object-to-be-controlled; and
synchronizing time between the three-dimensional data to be displayed, reproduced in the generation of the action reproduction simulation data, and data to be displayed in the processing, wherein
displaying the action reproduction simulation data on the display as three-dimensional data includes displaying the three-dimensional data on the display as viewed from a viewpoint position that is moved according to display setting information representing the viewpoint position for use when the virtual object-to-be-controlled is to be displayed on the display as the three-dimensional data.
