May be this is what you mean:

e=BinCounts[d,{0,xmax,1}]    (* which results from Poisson with freq y  *)
f=Sum[e[[y]],{y,1,xmax}]     (* totaal of the frequenties *)
g=N[e/f,2]		  (* relatieve frequenties, 2 cijfers precision *)
	,PlotRange->{0,1.5 ymax}]
	(*,Axes-> Automatic]*)  (* Plot of the Gauss-distr[av,root(av)] *)
poiss=BarChart[g, PlotRange -> {0,1.5 ymax}] (* idem of the Poisson[av] *)
	(* ,AxesLabel->"Klaswaarde,Klasfrequentie" *)

		,Automatic} ]

It is inspired by: "Applied Mathematica" by Shaw/Tigg, Addison Wesley page 361

Mutual assistance helps to survive=adapt=develop.
I send personal e-mail-copy for information,
