Re: [ferret_users] specifying plot line colors

["Ansley C. Manke" <ansley.b.manke@xxxxxxxx>]

Hi Keith,

A simple way to use only non-black colors on a line plot, is with 
PLOT/COLOR - with no argument to COLOR:

   plot/color var1, var2

That will use the firs two non-black default colors red and green. To 
use first blue and then red, you could redefine the colors with PPL COLOR

yes? ppl color,2,0,0,100  ! color number 2 becomes blue
yes? ppl color,3,100,0,0  ! color number 3 becomes red
yes? plot/color/i=1:15 var1, var2

The PPL COLOR settings persist through the Ferret session, or until you 
issue a SET WINDOW/NEW.  All of this applies to PyFerret and Ferret.  
Note that you can come up with other colors you wish, and also set up 
more than 6 different colored lines.  See this example:
