You don't happen to have any similarly clever tricks that would work on
Windows, do you? (Gnuplot on windows does not support capturing system(),
``, etc.)

I've seen requests before for an option to disable gnuplot warnings (not
errors, necessarily, as recovery could be tricky). The noise can be
excessive when running in batch mode to create a large number of plots,
where empty data files or single-value ranges (for example) are not
worrisome.

(Sorry if this comes through twice.)
