name several curves within a loop

Hello,

I am plotting about 80 curves on the same plot.

In order to differentiate between each curve, i would like to name each curve on the plot within the for loop shown below:

for k = 1:80
   [a,b]=test(a1,b1);
   labels = cellstr(num2str([k]')); % not sure about this one*bold*
   h=plot_curves(a, b, 'r',5);
   hold on
end

Thanks,

Ash

You could put a text on each curve. But placing the text could be tricky with that many curves on one plot.

x = 0:.01:1;
L = floor(length(x)/2);
hold all

for ii = 1:4
   plot(x,x.^ii)
   text(x(L),x(L).^ii,sprintf('%i',ii))
end

my entire curve is filling with the text. what might be the solution

 labels{k} = num2str(k);

Then at the end of the loop,

legend(labels)

This assumes that plot_curves is constructing exactly one line object per loop iteration.
