[Gnuplot-info] white out background of the key region

[Jon <dev...@gm...>]

Dear All,

I am trying to achieve the effect putting the key on some white background
although there is originally some plots there. How can I possibly do that?
I tried to define a region and then clear it within mutliplot, but that
area is always overwritten by the following plots, and thus cannot be
whiten out.

Thanks,

Sincerely,
Jon
