Re: Custom line colors

[Billy Kessler <William.S.Kessler@xxxxxxxx>]

I have been able to use a system something like Mick's, that works.
I don't have time to write a simple example, but here is the guts
of code that makes and uses 6 colors plus black, and has altered
the colors, too (see attached plot). pen 2 is reused in this plot
to make an ugly yellow.

plot/set/nolab/vs/line=1/sym=27/l=212:272/hli=-3:4:1/vli=-25:18:5 nino3smrg,z20av ! black
...
ppl plot
plot/nolab/vs/line=2/sym=27/l=177:212/over nino3smrg,z20av	! red
plot/nolab/vs/line=3/sym=27/l=158:177/over nino3smrg,z20av	! green
plot/nolab/vs/line=4/sym=27/l=143:158/over nino3smrg,z20av	! blue
ppl color,5,0,70,70
plot/nolab/vs/line=5/sym=27/l=89:143/over nino3smrg,z20av	! darker cyan
ppl color,6,70,0,70
plot/nolab/vs/line=6/sym=27/l=33:89/over nino3smrg,z20av	! darker magenta
ppl color,2,70,70,0						! reuse pen 2
plot/nolab/vs/line=2/sym=27/l=1:33/over nino3smrg,z20av		! yellowish

Gotta run, but this worked for me. Maybe a difference from Mick's
scheme is that I reset the color BEFORE each plot/over statement,
not between PLOT/SET and PLOT/OVER. And one essential is to reset
all the colors between each plot:

ppl color,2,100,0,0; ppl color,5,0,100,100; ppl color,6,100,0,100
