How do i select my frequency range to plot when fft is made on time domain
The Discrete Fourier Transform takes a signal from the discrete time domain to a discrete frequency one. In the process, it is possible to evaluate the DFT in less (or more) "frequency bins".

In the time domain, the signal is indexed by a variable that denotes discrete samples. For example $x[n]$ where $n$ relates to physical time by $n \cdot T_s$ where $T_s$ is the sampling period.

In the frequency domain, the spectrum of the signal is indexed by a variable that denotes discrete frequency. For example $X[k]$ where $k$ relates to physical frequency by $k \cdot \frac{Fs}{N_F}$ where $N_F$ is the length of the DFT.

So, given a signal that was acquired at $Fs = 44100$ Hz in a buffer that was 1024 samples long (that is the $x[n]$) which was then transformed by a 512 point DFT (that is the $X[k]$), the correspondence between $k \in [0 .. 511]$ and physical frequency $f$ would be $f_k = k \cdot \frac{44100}{512}$ or a spacing of 86 Hz.

You can then use this correspondence to choose which part of the spectrum you want to plot.

As a side note, your accelerometer board is pausing data logging to write the acquired buffer to an SD card or send it over some interface elsewhere. This creates very short zero value gaps, which, overall, are going to distort your spectrum into something that looks "wavy" in a very distinct way. In fact, your spectrum is effectively the spectrum of your vibration data as modulated at 100% by a square wave at whatever frequency is implied by the length of the buffer and the speed of the SD Card / interface of your data logger. Depending on how short your recordings are going to be and how they are timed, you are going to have to do something about this, otherwise your spectrum will not be the "real" one.

Hope this helps.
