Re: gnuplot background

[ Pavel asked how to change the gnuplot background color to white
  on Ubuntu 6.06, Octave 2.1.73, GNUPLOT Version 4.0. Since gnuplot
  default is normally white, Ubuntu must change this property. ]

If you invoke gnuplot directly (e.g. from the menu, or from the command prompt),
does it still have the black background? If so, that means that the background
property for gnuplot is set somewhere. Unfortunately, there are a dozen or so
places where X properties can be set:

       - specified upon invocation via 'gnuplot -bg black'
       - loaded from user's '~/.Xdefaults' file
       - loaded from some other general or gnuplot-specific X resource file
       - picked up by gnuplot upon startup from somewhere

You can check the currently installed global properties by 'xrdb
-query': search for properties related to gnuplot and/or general
Background properties.

The properties mechanism in X is pretty frustrating---debugging
problems like that is rather annoying, sorry.
