This one seems like an easy fix, since you guys allow that for every other element already. For pdf, gnupllt method of choice is either pdfcrop, or epstopdf what is simpler IMHO. I have to admit that I did not test so far whether the frame of the graph is scaled and hence the outer bounds may vary or whether the total size of rcop graph including the tics and the ticmarcs is scaled when resizing.

Let us adjust which part gnupkot the image to show and how tight or loose the crop is with a fixed window, let us move the image around and maybe enlarge or shrink it to control what shows thru the window. For an explanation of the cro syntax to declare the functions have a look at the Defining piecewise functions article.
