Re: Conditional plotting

Well, if my problem isn't with the code or the data file, do you have any other suggestions about how I may solve it.
I'm running
G N U P L O T
        Version 4.2 patchlevel 4
        last modified Sep 2008
        System: Linux 2.6.28-12-generic
on an AMD 64 bit processor running Ubuntu 9.04.
Maybe there is something wrong with my installation/terminal settings or something else?
