I am trying to do a nice animation. Here it is << Graphics`Graphics` Env[x_] := (Cos[Min[Abs[x], 1]*Pi]/2 + 1/2) ShepFrame[order_, frac_] := Module[{g1, g2}, g1 = Plot[Env[t], {t, -1.1, 1.1}, DisplayFunction -> Identity]; g2 = GeneralizedBarChart[ Table[{(frac + i)/order, Env[(frac + i)/order], 0.025}, {i, -order, order - 1}], DisplayFunction -> Identity]; Show[g1, g2, DisplayFunction -> $DisplayFunction, AspectRatio -> 0.3, ImageSize -> {500, 200}]] Do[ShepFrame[3, t/100], {t, 0, 100}] It works, but the animation is jumpy, the bare change their widths wich they should not. Is there an easy way of making the animation smoother?
