Oookay! I wrote "plot x*x" and it went flawlessly. However, since "plot x^2" was bad input, gnuplot sent an error message to me before. This just didn't come through to me correctly - which means: the output was only partly there or scrambled. Maybe buffering (although pipes are not buffered)? Maybe something else? I will try again when I've time.
