%Define draggable sources
set(dd,'DragHandles',[drag1 drag2]);

%Define drag targets
set(dd,'DropHandles',[drop1 drop2]);

%Define callbacks
% We want different functionality depending on which axes the button is
% dropped onto.  Dropping on the top axes will create a 2D plot, while
% dropping on the bottom axes will create a 3D plot.  We set DropCallbacks
% to a cell array, with the elements of the cell corresponding to the drop
% targets set in DropHandles.
