MATLAB: How to change color each loop

graph color change

I have a program which should be repeated 5 times by a loop. I used plot() order in my program and I'm eager to change graph color each time. How can I do it?
For example:
    plot(ZZ,dTdz3,'.',h,t,'y')
I want to change 'y' to 'm' in the next loop.
note: ZZ and dTdz3 are matrices and h and t help me make a line, none of them looks important in my question to you.

Best Answer

Use the 'Color' option of plot:
ZZ = 1:5;
for k = 1:10
  dTdz3 = rand(1,5);
  plot(ZZ,dTdz3, 'Color', rand(1,3), 'LineWidth', 3)
  hold on;
end
