Sorry to be a pain. Maybe I just don't understand how this works. I've searched everywhere, and still can't locate the executable. The executable should be called gnuplot. According to the install file in the package, it might be in a subdirectory called /gnuplot/bin, but looks like it depends on settings during compile. According to the FAQ section of the website, it says it might be in /usr/local/bin. I have no idea what to do since I cannot view the server's filesystem to find it. I've tried all these combinations and others, and haven't found a path that works yet. Any help would be greatly appreciated.
