Dear all
As you know, legend(axe_handle, 'legname') can link the relation between legend and axes, I mean that you can get legend handle with the command legend_handle = legend(axe_handle).

However, when copy axes and legend to a new figure, this relationship was lost. Here is an example code to illustrate my statement.
function retchar = test()
close all;
h1 = figure;
ha = subplot(1,1,1);
plot([rand(10,1), rand(10,1)], 'parent', ha);

leg1_handle = legend(ha, {'china'});

h2 = figure;
na = copyobj(ha, h2);
leg2_handle = copyobj(leg1_handle, h2);

retchar = sprintf('1st is: %f, 2nd is: %f', legend(ha), legend(na));
return;

when run: test, you can get:
1st is: 312.003174, 2nd is:

the 2nd is nothing :)

so, my question is how to set relationship between legend and axes?

best regards

copyobj is somewhat notorious for not actually creating an exact copy of the original object.
Search the Bug Reports for copyobj and you'll see a few of the known limitations.

In this case you can see the incomplete copy by looking at the UserData of the handles,

>> get(leg1_handle,'UserData')
>> get(leg2_handle,'UserData')

You should submit a bug report.

Phil.
