Hello.

I have gnuplot 4.6.0 on Windows 7 64 bit Professional.

I have big input file (test.plt in attachment). When it is loaded in wgnuplot, it works OK, charts are shown. But if I feed it as STDIN to pgnuplot:
"C:\Program Files (x86)\gnuplot\bin\pgnuplot.exe" < test.plt
no charts are built, and input in wgnuplot window is corrputed (it seems that some CR are missed).

  • Now that we have a real console version of gnuplot on Windows, too (gnuplot.exe), there's not really that much point in using pgnuplot.exe any more. I suggest you switch.

     
  • I tried to switch, but I could not get persistent window with chart on windows terminal.
    "C:\Program Files (x86)\gnuplot\bin\gnuplot.exe" -p - < test.plt
    lead to chart appearing and immediately closing before a chance to look at it. With pgnuplot it works as desired, but it has the bug reported here.

    Why use redirection for that? It should work better without.

     
  • It does works without, but my real gnuplot script is created by another script with Ruby gnuplot library, and it tries to feed it to gnuplot via stdin. Maybe there is a way to use temp file, but I do not know it, and it is not convenient anyway.

     
  • The CVS version of gnuplot includes a console mode version (gnuplot.exe) which supports pipes, a windowed version (wgnuplot_pipes.exe) with support for pipes, and the (traditional) windows version (wgnuplot.exe) with (fake) pipe support from within the program. Should version 5 really still include 'pgnuplot' to pipe to wgnuplot.exe?

    In other words: I am proposing to remove pgnuplot in the next release altogether. Objections?
