Re: Custom line colors

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

I also tried Jaison's script, on a Sun Blade running Solaris 8 and
Openwindows, and found that the colors of previously-drawn lines 
became recolored after a few lines were drawn. This is from a new 
Ferret session with no resizing or reshaping of windows.

This led to an amusing experiment:

1) Make Jaison's script, test_colors.jnl:

ppl color,$2,$3,$4,$5
plot/i=1:100/over/color=$2/line/nolab sin(3.14*i/100)-$1/100

2) Give the following commands in Ferret:

plot/i=1:100/col=1/line/nolab sin(3.14*i/100)	! initial line
repeat/j=1:100 go test_colors.jnlb `j` 3 `j` `100-j` `100-j`

Or for something even stranger:

repeat/j=1:100 go test_colors.jnlb `j` 3 `abs(100*randn(j))` `100-abs(100*randn(j))` 
`100-abs(100*randn(j))`

Fun with computers ....

But this makes me agree with Lynn that only 6 new colors can be used.
