Create legend within a for loop but with changing size of plot handles

Hi all,

I have a plot within a for loop, plotting 22 line objects on the first run (i=1) and 28 line objects on the second run (i=2). I would like to have a legend that has the a line object from the first run and a line object from the second run.

Sounds simple, however as the handle sizes are changing, i cant seem to be able to save them in a cell array so that I can call them afterwards e.g.:

 for i=1:2
    hold on
    p(:,i) = {plot(...22 line objects for i=1 and 28 for i=2...)} ;
    hold off
 end
 legend([p(1,1) p(1,2)],'first run','second run')

The result is a cellarray p={[epmty] [28x1 line objects]} which means that for some reason the handles from the first run are not being saved.

Thanks for your help in advance,

KMT.

p{i} = plot(...)

would seem a more obvious way to fill a cell array, though whether this will solve the problem or not I don't know. I don't see why your first element would be empty other than because the plotting of 22 objects is not actually returning any handles, which will be the same whatever assignment syntax you use.

 for i=1:2
    hold on
    p{i} = {plot(...22 line objects for i=1 and 28 for i=2...)} ;
    hold off
 end
 legend([p{1}(1), p{2}(1)], 'first run', 'second run')

Thanks for your answer!

Again, the same problem arises. the vector p is returned as:

 p = {[] {1x1 cell}}

which means that for some reason the results from the first iteration are not saved

Difficult to say without the actual code.

In your line

      p{i} = {plot(...22 line objects for i=1 and 28 for i=2...)} ;

do you mean that you literally have plot() called within {} ??
