This will do the trick.

GraphicsCell[gr_] :=
   Cell[GraphicsData["PostScript", DisplayString[gr]],"Graphics"]

ReplaceGraphic[gr_] :=
   Module[{nb=EvaluationNotebook[]},
     SelectionMove[nb, All, GeneratedCell];
     NotebookWrite[nb, GraphicsCell[gr]]
   ]

AnimateInPlace[{first_, rest___}] :=
   (CellPrint[GraphicsCell[first]];
     Scan[ReplaceGraphic, {rest}])

Try it out.

grs=Table[
       Plot[a x/10, {x,0,1}, PlotRange->{0,1},
         DisplayFunction->Identity],{a,10}];

AnimateInPlace[grs]
