That error message is not specific to gnuplot.
It means that your X-server is refusing to talk with the
current process.  

This probably means that you have the security level set so
high that only the same user who initiated X is allowed to
communicate with the server. That is actually a good idea.

But you tried to run gnuplot as root, and root!=original_user,
so the X communication was refused.  You would probably have
gotten the same error with any other X program (e.g. xterm).
