Here is what I am doing:
(use posix)
(define gnuplot-pipe (open-output-pipe "gnuplot"))
(define-macro (gnuplot . args)
`(begin
(for-each
(lambda (arg)
(write arg gnuplot-pipe)
(display " " gnuplot-pipe)) ',args)
(newline gnuplot-pipe)))
(gnuplot plot x)
(gnuplot replot 2*x)
(close-output-pipe gnuplot-pipe)
I am executing this line-by-line from emacs. The problems is that
all the plots are shown only at the end, when I close the pipe, and
they immediately disappear. In other word, a buffeting problem.
I tried to set (define pipe/buf 0) but I had no visible change.
Any suggestion?
