dyn analysis displacement graph help

[Chris_M]

I am doing a simple cantilever beam analysis with a shock acceleration curve. i have measures placed at end of the beam. my acceleration graph looks mostly correct with a decaying sine curve but my displacement graph is increasing linearly instead of the offset decaying sine curve i would imagine. any thoughts of what i did wrong?

i figured it out. the displacement, acceleration, velocity relative to box was set to ground and needed to be on supports that is found on the output tab.
