Re: [Gnuplot-info] change of line colours when upgrading gnuplot

[Jelle de J. <jel...@po...>]

I came a bit further by looking at the generated eps files.

I found the bellow default colors (this whole block is not present with
the old generated eps with gnuplot 4.0 patchlevel 0) and if I change the
values in the eps file the lines color will change. So I am looking for
the behaviour of gnuplot 4.0 patchlevel 0 (this was the old working
version).

Is there a way to not have the default line colors present, or otherwise
what is the way to set the default line colors to other values, because
altering them may be a workaround.

gnuplot 4.6 patchlevel 2

% Default Line colors
/LCw {1 1 1} def
/LCb {0 0 0} def
/LCa {0 0 0} def
/LC0 {1 0 0} def
/LC1 {0 1 0} def
/LC2 {0 0 1} def
/LC3 {1 0 1} def
/LC4 {0 1 1} def
/LC5 {1 1 0} def
/LC6 {0 0 0} def
/LC7 {1 0.3 0} def
/LC8 {0.5 0.5 0.5} def

gnuplot 5.2 patchlevel 4

% Classic Line colors (version 5.0)
/LCw {1 1 1} def
/LCb {0 0 0} def
/LCa {0 0 0} def
/LC0 {1 0 0} def
/LC1 {0 1 0} def
/LC2 {0 0 1} def
/LC3 {1 0 1} def
/LC4 {0 1 1} def
/LC5 {1 1 0} def
/LC6 {0 0 0} def
/LC7 {1 0.3 0} def
/LC8 {0.5 0.5 0.5} def

Kind regards,
