Hello,

for me string variables being hard. I can't found a way to set "lc" and
"fc" as string variables.

example:

color1 = "red"
color2 = "green"
set obj 1 rect from 0,0 to 5,5 fc color1
set obj 2 rect from 0,0 to 5,-5 fc color2
plot sin(x) w l lc color1, cos(x) w l lc color2

How must I define the variables?



set obj 1 rect from 0,0 to 5,5 fc 'red'
set obj 2 rect from 0,0 to 5,-5 fc 'green'
plot sin(x) w l lc 'red', cos(x) w l lc 'green'

This works, but there are much lines and much rectangles. So it will be
easier to change the color if I can define them as variables.



Thanks for any help,

Jörg
