XY plot requiring different input types limits usability

[adalast]

So I am used to using S/R for my XY plots in A1111 to do things like comparing style prompt tokens on one axis with modifying adjectives on the other. That way I can see something like a "[Dark, Gloomy, Foreboding] graveyard with a [anime, gothic, classical] style" looks like. I can understand not allowing 2 nodes the vary the other parameters being allowed, but S/R really should be exempt as it should not normally interfere with itself, unless someone is a moron and tries to have it search the same word, but that should be trivial to capture and throw an error in that case.

@adalast That patch should work:
