I think you may have to do it manually in case you do it only with Gnuplot.
However, there is a MatLab clone called Octave
( http://www.che.wisc.edu/octave/ ) that uses GnuPlot for all plotting. As
Octave is a programming language, a few lines of Octave code can allow you to
place a string at the desired location. What follows is one such script
written by me that types in an integer z at (x,y) on the plot.

If you want to print a string 'z' at (x,y), you may have to modify the script
accordingly. I have listed the code below...

Best wishes,
