# Same colour for two curves in a plot

1 view (last 30 days)
Hi MATLAB Community,
I need to have the first and third cuve the same colour, how do i do that?
I would really ppriciate some help on how to do that.
a = [ 100, 65, 95];
b = [-100, 65, 90];
c = [50, 20, 20];
d = [-25, 20, 20];
x = linspace(-200, 100, 200)
for k = 1:numel(a)
y(k,:) = a(k)+b(k)*tanh((x+c(k))/d(k));
end
figure;
plot(x, y);

Something like this. You'd just have to pick the colors you want.
h=plot(x,y);
set(h, {'color'}, {[1 0 0]; [1 0 1]; [1 0 0]});
Thanks, that worked perfectly. Exactly what I was looking for. An easy solution, I will definitely remember in the future. I appricate the help.

you can also use color instead of triplets
h=plot(x,y);
set(h, {'color'}, {'r'; 'b'; 'r'});
Thanks, that is great information to have. appreciate it a lot.
Can you make it dashed as well?
