A system according to an embodiment is configured to display program execution results with respect to a common axis. The system includes a first unit that acquires event information about two or more events, acquires reference-event identification information to be used in identifying reference events, and generates event objects which represent the events, and a second unit that acquires axis information which represents information about the common axis. The event information contains timing information indicating positions of the events. The first unit sets the reference events as references for the program execution results based on the acquired reference-event identification information, determines display positions of the reference events with respect to the common axis to be same position based on timing information in event information about the reference events, and generates event objects representing the reference events based on the determined display positions with respect to the common axis.
