I'd like to see the raw data transformed into the frequency domain with matlab

I am not a EE, but I understand the need to analyze the signal in the frequency domain. I guess my concern is if the signal, the oscillations, are well characterized at the given sampling rate. You guys are saying, yes. Fine. I'm saying more couldn't hurt.
The more significant issue is which part of what has been measured during the shift and displayed in the first graph is the signal, and which part is the noise? Those two spikes can't both be entirely signal. What is the frequency of the signal vs the noise during that interval? Anyway, that'll hopefully clear up once the sensor is mounted properly.
