I'm trying to tune the very low frequency resonant frequency of a vibration sensor. When I run the FFT it shows 8K Hz in the top right corner, but the frequencies I'm interested in are the far left 3 pixels, which isn't enough detail for me. Can I "zoom" in the frequency/horizontal access to be perhaps 200 Hz, or even 1K Hz? I looked but haven't been able to figure out how.

Thanks!
