What I'd Like to Do: I'd like to modify x-axis range of the plot produced by the "Plot Spectrum" Analysis plug-in. I only want to see frequencies < 500Hz.
Why I Want To: The analysis I'm doing only requires me to look at lower frequencies, so visually it would help me to only see the lower frequencies. I know this won't change the actual resolution of the FFT, it's only for display purposes.
What I Already Tried: According to the audacity wiki, most of the plugins are implemented in nyquist. Unfortunatly, "Plot Spectrum" doesn't appear to be one of them, it's not in the `plug-ins` folder.
