Re: [Gnuplot-info] Color-graded line?

[Thomas P. <pfr...@ph...>]

Thanks for this help! Thats great!

If I want to fill the area between the 2 curves, I already use 3 
arguments for using, and filledcu does not accept a fourth for the color 
palette. In there a workaround for the filledcu option and still use the 
following command?

lc palette z

Thanks
Thomas
