Christine,

The error:

   warning:GKS:GOPWK: --X driver error: error opening display

indicates that either you don't have an X11 server running, or you
don't have your DISPLAY environment variable set, or it
is not set correctly.

It's probably a DISPLAY problem, so see:

   http://www.ncl.ucar.edu/Download/install.shtml#SetDISPLAY

for information on this.

Meanwhile, if you don't care about displaying your graphics to an X11
window, you can force the output to go to a PostScript file with:

   ng4ex -W ps xy04n

This should create a PS file called "xy04n.ps".
