Changing Colors in a Plot Using a For Loop

Here is my code.

Z=[3 1 7];

for i=1:length(Z);

A(i)=Z(i)+2

B(i)=Z(i)-7

C(i)=Z(i)+4

col=['g' 'b' 'r'];

for j:length(col)

x=[1 2 3];

y(:,i)=[A(i) B(i),C(i)];

subplot(3,1,i)

plot(x,y(:,i),'color',col(j))

end 
end

My last line of code is failing to change the color on the plots. All of the plots end up red. I want one of the plots to be green, one to be blue, and one to be red. How can I fix my code?

They will be if you change the ‘col’ subscript from ‘j’ to ‘i’:

plot(x,y(:,i),'color',col(i))

because you subscripted the subplots by ‘i’.
