I guess my problem is I started with 3.7 and those commands definitely do NOT work:

version strings are written to stderr (except for 'gnuplot -V'),
that's one of the problems. something that should work on all platforms and versions: echo save \"filename\" | gnuplot and then read the file in and parse it.

The 'save filename' trick does not work on windows, at least not with v4.2. All it does is run gnuplot. I don't plan to lose too much sleep over this one, but rather was just wondering if there are any tricks I might have missed.

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.

Actually, no, pgnuplot is not supposed to help with that. pgnuplot pipes its input go wgnuplot. There's nothing it could do to pick up any stdout output --- wgnuplot simply doesn't have any stdout. ------------------------------------------------------------------------------ _______________________________________________ Gnuplot-info mailing list Gnuplot-info@... https://lists.sourceforge.net/lists/listinfo/gnuplot-info |
