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.
