From: ragab Rabeiy on 15 Jun 2010 07:09 Dear All, I need help in plotting. I want to plot 6 lines in one figure from a loop code. i did that, but all the lines have the same color and symbol. i need that, every line has different color and symbol. see this code: clc clear close all ind=1; for j=1:6; for x= 400:400:20000; t =0.5*sqrt(x)+10*j; plot (x,t,'-bs') ; hold on; grid on; ind=ind+1; end end Greetings Matlab-beginner,

One of many solutions: x= 400:400:20000; marks = ['+','^','o']; colorz = ['b','k','r']; t = zeros(length(x),3); for j=1:3; t(:,j) =0.5*sqrt(x)+10*j; line(x,t(:,j),'linestyle','-','marker',marks(j),'color',colorz(j)); end I only did 3, but you can generalize. Hope that helps, Wayne
From: Debanga Neog on 15 Jun 2010 08:15 Hi, This can be a generalized solution: x= 400:400:20000; marks = ['+','^','o']; colorz = ['b','g','r']; t = zeros(length(x),3); N =5; for j=1:N; t(:,j) =0.5*sqrt(x)+10*j; line(x,t(:,j),'linestyle','-','marker',marks(mod(j,3)+1),'color',colorz(mod(j,3)+1)); end Thanks to W. King!!! -DRN
