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.
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.
