ok, i managed to find a windows system with gnuplot 4.2 so, wgnuplot doesn't deal with pipes, but pgnuplot should, but i don't get anything on stdout. anyway, you are searching for something which works everywhere, so that's what i found to be compatible even with wgnuplot: write a file 'test.plt': save 'test.log' exit and then run gnuplot: wgnuplot test.plt this will create the file 'test.log' which you may open and parse.
