How to plot multiple fitted curves in single plot with different colors and legends

Hi all,

I am trying to plot multiple fitted curves in single plot using for loop. I wish to have different colors for each plot (or atleast for each fitted line) along with all legends.

Kindly help!

Thanks!

for cf = 1:3 
    AHG_final; % a, b and Name comes from 'AHG_final' script
    loga = log(a);
    fitc = fit(loga',b','poly1');
    plot(fitc,loga',b');legend(['River',sprintf(' %d : ', cf), sprintf( Name)]); 
    xlabel('log a'); ylabel('b'); title(['River',sprintf(' %d : ', cf), sprintf( Name)]);
    
    hold on;
 
end

You can predefine your colors for example as

colors = {'r','g','b'};
% or
colors = colormap(jet(3));
% etc.

and than in loop

h = plot(fitc,loga',b');
set(h,'Color',colors{i});
