[Gnuplot-info] Change colour of key text

[babelproofreader <bab...@gm...>]

With the script below I have set the background colour of the plot to black,
but the problem is that the text in the key and the grid lines are also
black and so can't be seen. How can I change the key text and grid line
colours so that they can be seen?

reset

set title " $1 Prices with Kalman filter"
set datafile separator ","
set key top left
set xdata time

set timefmt "%d/%m/%Y"
set grid
set object 1 rect from graph 0, 0, 0 to graph 1, 1, 0 behind lw 1.0 fc rgb
"#000000" fillstyle solid 1.00 border -1

plot "$1ind" using 1:2:3:4:5 notitle with candlesticks lt 9, \
"$1ind" using 1:24 title 'Optimum kalman' with line lt 1

use gnuplot version 4.4:

set style line 99 linetype 0 linecolor rgb "#ffffff"
set key top left textcolor linestyle 99
set grid linestyle 99
set object 1 rect from graph 0, 0, 0 to graph 1, 1, 0 \
   behind lw 1.0 fc rgb "#000000" fillstyle solid 1.00 border -1
plot sin(x)

There are, of course other ways of doing this in earlier gnuplots,
depending on the terminal chosen.  PNG, for example has a syntax that
allows background, foreground, and other colors to be specified. I have
found that black-background graphs are especially stunning visually and
have converted all my graphs to work that way.  I suppose this might not
work so well for printing.
