I wrote a Python program, which calls Gnuplot to export image files. For every plot, my stderr got warning messages such as

gnuplot: unable to open display ''
gnuplot: X11 aborted.

I knew I can redirect these to /dev/null, but I do need my stderr for other purposes. I wonder if there's an Gnuplot option to turn it off.
