    Trying to run gnuplot in CentOs 5.2 gives me this error - advice appreciated.

    This is gnuplot version 4.0. Please refer to the documentation
    for command syntax changes. The old syntax will be accepted
    throughout the 4.0 series, but all save files use the new syntax.

    Terminal type set to 'x11'
    gnuplot> plot sin(x)
    gnuplot: unable to open display ''
    gnuplot: X11 aborted.*

    I know this is an old version. This is what I get from a # yum install gnuplot

    I figured to make things easier, I would get this running, then upgrade later.

    Thanks.

     
  • The problem has nothing to do with the version of gnuplot.  You installed an X11 version of gnuplot, but apparently you don't have a working X11 on your box.  That can't work.

    Now I don't know much about this  "yum" thingy, but it's obviously quite broken.  What good is a package manager if can't even detect a blatantly obvious conflict as that?

    I understand the problem will reveal itself to be one of ignorance on my part, and I appreciate your guidance.

    Yes, I do have X11 installed and fully functioning on my CentOs 5.2 setup. In fact, gnuplot runs nicely from my Gnome desktop. However, I am trying to get it to run from a PuTTY connection. It appears I might be able to do this with Xming, maybe that's my only option, but I hope not.

    Then it has nothing to do with Gnuplot: you should forward X connections as well.
    Question: do you connect with putty via ssh? If so you should use something like "ssh -X you@yourcomputer"

    Then the question whether the server will or will not enable X connections opens.
