this is a cite from another email, i wrote today. feel free to adjust it to yours:
PS: for some reason, your email appears to be a part of the thread "pd *is* a programming language". if this is by chance, ignore the following: it is considered bad style to randomly pick an email from the pd-list (or - in general - any mailing list) and "reply" to it with changing the subject and the body. read http://puredata.info/community/lists/netiquette (search for "threads") for more information on this.

[tabwrite] will do what you want. you have to manually walk through the x-axis though (unlike e.g. "sinesum").
you could plot either (or both) the idealized function or a measured one. (though the latter takes more time, so you probably won't want it)
