THD in LTspice?

I've recently been using this, and can't recommend it highly enough:

I believe the author was on this forum a while ago... in any case, they deserve a lot of credit for this. It's far easier then thinking about the measurements yourself, and is very well documented.

I've just found that script and I'm trying to understand how to use it properly.
Can someone tell me how I can plot the THD vs freq graph with that plugin?
After I've simulated the given example , I went to the error log (CTRL-L) and than I right clicked on that window.
THD vs output amplide graph appear after I select "plot selected meas data"
I have even changed the analyzer_controls.txt commenting the amplitude sweep and uncommenting the freq sweep but the result doesn't change: I cannot display the THD vs freq graph I'm looking for.
Cheers
