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

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

Thanks Trait,

It really does not automatically white out its background. I checked the
gnuplot help, but it does not have the option of opaque, and the default
does not white out the background.

I tried

set object rectangle from 0.5,-0.0175 to 1,0.1 fillcolor rgbcolor "white"

but it does not even white out anything. Actually, I cannot understand the
logic.

As far as I understand gnuplot, it saves effects in the ordering when they
appear and then gnuplot plots according to this effects. I can set
something, they will not appear until I issue plot command. That means plot
command is always latest to any effects defined before, thus nothing can
cover it unless specifically defined in the manual, say, set object
rectangle specifically says it will remove any lines etc (no matter where
the command is issue) but leaves labels intact.

Thanks for further help,

Sincerely,
Jon
