The object "g" will be deleted when the scripts ends. When
that happens, the gnuplot process is killed. All this probably
happens before the plot window has been mapped to the display.
Add something like "sys.stdin.readline()" to the end of the
program so that it doesn't exit until you hit "Enter".
