MATLAB: How to get handles of a legend that was automatically generated

Question

I am trying to move an automatically generated (did not create command like: lgd=legend(…)) legend in a subplot.

How to access that legend? so that I can use lgd.location=best.

Also, legend moving sometimes disturbs axis extents, how to avoid that? ————————

Edit1: I am using following code to generate plot that generates automatic legends:

parallelcoords(P1to5,'Group',...
    Group1to5,'Labels',Labels1to5);

Answer 1

H = findobj('type','legend')
H.Location = 'best'
