Vim doesn't remember the file type. When you open a file it
checks if the file matches certain criteria and then sets the
file type (:h filetype for more information).
You can fix this by either writing special rules to detect
gnuplot files (by having a look at the content) or by using the
correct extension (.gpi for gnuplot) which Vim can detect.
You can use a different extension of course by adding this to
your vimrc:
au BufNewFile,BufRead *.extension-here setf gnuplot
