Ya...my concern was in moving the rectangle (rather dragging it to pan the main canvas view). I am now able to do it almost the way I wanted but in a different way...using the rubber band zoom function the Canvas2 and applying the effect in Canvas1...works like a charm :) 
## $can is the canvas displaying the main graph and $can_1 is the cont
+roller canvas...

  $can_1->configure(-bandColor => 'orange');
  $can_1->CanvasBind('<Button-1>'               => sub {$can_1->Canvas
+Focus; $can_1->rubberBand(0)});
  $can_1->CanvasBind('<B1-Motion>'       => sub {$can_1->rubberBand(1)
+});
  $can_1->CanvasBind('<ButtonRelease-1>' => sub 
{
my @box = $can_1->rubberBand(2);
$can->viewArea(@box) 
});

Thanks for all the help I got....Happy coding
