Re: changing the color of curves continuously

[Robert A. Macy]

More colors than that.

try this...

>> x=randn(50,16);plot(x);

you will see a wide range of colors

or easier viewing...

>> x=randn(1,10);plot(x);hold on;for
i=2:16;plot(x+i-1);endfor;hold off;

from experience at trying to discern which plot line is
which on a 50 line plot [yes, colors are repeated], you
don't want more than a few basic colors, after that start
putting little symbols in there.
