Copying a matplotlib canvas (or a figure, or an axes) is not easy. You cannot just rebind it. You need to copy all the hierarchy of underlying artists. Also the attributes of artists need to be adjusted accordingly. And best option in my opinion is just to create another canvas using the code that created the original canvas.
