 When calling QP.drawLines you can optionally pass the containing div as an argument in order to draw lines for only that query plan.  You should also make sure that this function is called after the page has fully rendered and the containing div is visible, for example:
 
     $(document).ready( function() {
-      QP.drawLines(&("#qpDiv"));
+      QP.drawLines($("#qpDiv"));
     });
 
 Normally the document ready event is suitable, however if the containing div is not visible by default then you will need to make sure that you call this function when the div is made visible.  (No harm is done by calling when the div is not visible, it simply won't draw the lines correctly).
