Simulation Shock Analysis Displacement Frequency

I ran a frequency analysis on an assembly, and then copied the study to a linear dynamic response spectrum analysis, and ran 30g shock from 0-2000 hz.

In the results at the end of the list of amplitudes, one displacement plot was generated.

I am not seeing how this ties in to the associated frequency, and if by this being the only displacement listed, it means it is the worst case.
