For greatest control over this sort of thing you'll need to edit
the gnuplot commands (save the graph "as an icon" first then
right-click on the icon). Then you can add lines defined
parametrically. See
http://t16web.lanl.gov/Kawano/gnuplot/parametric-e.html
especially the section "to draw a vertical line".
