DisplayName when plotting matrices

Question

I don't seem to be able to set the DisplayName of a bunch of lines at once. For example,

h = plot(rand(3),'DisplayName',{'1','2','3'});

does not work. Similarly, I can't get the set command to work on all the lines at once. The only way I manage to do it is with a loop:

h = plot(rand(3));
for ind = 1:3
    set(h(ind),'DisplayName',num2str(ind))
end

Is that the only way?

It can be a nuisance to get the syntax right, but it is possible to change the DisplayName in bulk. But not using the 'DisplayName' option of plot()

h = plot(rand(3));

set(h, {'DisplayName'}, {'1'; '2'; '3'})
