granularity of spectrum analyzer

[sonnichs]

I am trying to plot spectra for musical instruments. When I select the analyze:plot spectrum option the plot extends to about 20kHz. I want to plot details in the 0 to 5kHz with a granularity of about 10Hz. I cannot seem to do this. I tried exporting the data and it is incremented at about 100Hz.

1) Is there a way to set the x axes to only show 0-5000Hz spread out over the complete plot
2) Can the granularity of the analyzer be increased to about 10Hz?

Thanks,
Fritz

If you use the "Change Speed" effect with a setting of 100%, then all frequencies will be doubled.
Apply it again and the frequencies will be doubled again.
Repeat as necessary.
Plot the spectrum, then divide all frequencies according to how many times faster it now is. For example, if it is now 4 times faster, divide all frequency values by 4.
