Since IPC::Run was not installed on my system, I tried the open method first. The close of GNUPLOT fails and $! is empty. I guess it's failing because I'm trying to close it with some data still buffered but why no error message?

I also put some invalid options in the gnuplot command to be sure that it is returning an error message. But @output is empty. The message is probably still buffered in GNUPLOT. Is there a way to flush it?

Thanks,
Bret
