The only caveat is that you have to write some sort of "script file" for it to be effective. You can use it in the interactive mode and do simple plots. But if you would like to add labels and such it would be easier to put in in a gnuplot script file. I actually think this is more powerful than a GUI application. Here is an example of a GNUPLOT script file.

Thanks, Amit. I've played with it for just a few seconds but I've got
to run... The graph seems to appear and disappear within a nanosecond.
When I have more time I'll google the situation.
