Hello Every one.I am using loop to get 14 plots at one figure.I need to have 14 legends.But the colours for the plot keep repeating.Please look at the picture.Is there any way I can get the separte color for each plot,or can get different nature of plot(dotted lines,dashed lines etc)

Try something like this:
y = linspace(0,50,50); % Create Data
v = 1:14; % Number Of Curves
x = sin(v(:)*y*2*pi) + 2*v(:); % Create Data
cm = colormap(jet(numel(v))); % Define Color Map
hold on
for k = 1:numel(v)
plot(x(k,:), y, 'Color',cm(k,:)) % Plot Each Vector According To The Colours In ‘cm’
hold off
The colours will not repeat unless you want them to do so. You can use any colormap you want, or you can create your own.
