How to show '@' in title with gnuplot and the output format is png?

问题

Do you know how to show the character '@' in the title when using gnuplot and the output format is PNG image? Thanks,

Which version of gnuplot are you using? Using gnuplot 4.4.3 with the following script:

#!/usr/bin/gnuplot

set term png 
set output 'plot@.png'

set xlabel 'xlabel is @'
set ylabel 'ylabel is @' 
set title "title is @a\'\@\'a\@"

plot x t 'line title is @'

gives me this image:

Even playing with escape sequence characters doesn't seem to pose a problem, and the file created has an '@' in the filename.
