As this test can be exectuted as many time as the user wants, I would like that if one frame already exist ( created by a prvious positive test) it is
destroyed before a new one is created.

instead of making $frame a lexical which is valid only inside the block, declare it outside the block.

        our $frame;
        if (...) {
                $frame->destroy if defined $frame;
                $frame = Gtk2::Frame->new (...);

but really, if you are wanting to replace an existing plot with a new one every time through, you probably want to keep the frame around and merely replace its contents.
