Sorry about that! The Emacs version is:

GNU Emacs 23.1.1 (i486-pc-linux-gnu, GTK+ Version 2.20.1)
 of 2012-05-18 on roseapple, modified by Debian

Working under Ubuntu 10.04 LTS.

When I open a buffer with M-x shell and subsequently give the gnuplot 
command everything works as expected. The plot window persists.

When I open a shell buffer C-x C-f try.sh and enter the same gnuplot call 
it does produce the plot window (after making the saved bash script 
executable) and executing it with C-c C-x but this does not persist. The 
interpretation buffer contents after execution is:

-*- mode: compilation; default-directory: "~/" -*-

Hope this helps.
