Gnuplot stop plotting in Mountain Lion

After upgrading Lion to Mountain Lion, GNUPLOT stop plotting the stuffs. I already downloaded XQuartz as Mountain Lion doesn't include X11 and Aquaterm isn't supported in Mountain Lion. XQuartz can be downloaded from here.

To get plot using Gnuplot, I just added

                               export GNUTERM='x11'

to my .bash_profile
Now Gnuplot start plotting. That's great...助かりました。
