How do I change the background color in gnuplot?

Question

I have a script that renders graphs in gnuplot. The graphs all end up with an ugly white background. How do I change this? (Ideally, with a command that goes into a gnuplot script, as opposed to a command-line option or something in a settings file)

Answer 1

You can change the background color by command set object 1 rectangle from screen 0,0 to screen 1,1 fillcolor rgb"green" behind to set the background color to the the color you specified (here is green).

Ooh, found it. It's along the lines of:

Answer 3

It is a setting for some terminal (windows use background). Check out colorbox including its bdefault.

Answer 4

According to the official documentation, as of version 5.4 the right way to set the background color in a gnuplot script is something like the following:

set term wxt background rgb "gray75"

Note that the color must be quoted. Beside color names you can use hex values with the format "#AARRGGBB" or "0xAARRGGBB
