Anyone has a guess why the Function TransformGraphics3D from the package Graphics`Graphics3D` does not show up in the Help index or anywhere else? ("TransformGraphics3D[graphics3d, f] applies the function f to all lists of coordinates in graphics3d.") It is the key to make the StackGraphics function usable. StackGraphics stacks n plots in the y-direction at i/n, i.e., between y=1/n and y=1. If you want to use the y-axis with some meaningful numbers you have a problem. TransformGraphics3D can solve it. The following is not very beautiful, but it works. Suggestions welcome! In[11]:= <<Graphics`Graphics3D` In[62]:= y=Range[3,6]; (* some y values *) In[58]:= plots=Plot[# Exp[-(x-#)^2],{x,0, 10},DisplayFunction->Identity]&/@y; (* some sample plots *) In[15]:= yScale[y_,lst_List]:= With[{n=Length[lst],f=First[lst],l=Last[lst]},((l-f)n y+n f -l)/(n-1)] (* scaling the y-axis*) In[64]:= Show[TransformGraphics3D[ StackGraphics[plots],{#[[1]],yScale[#[[2]],y],#[[3]]}&], PlotRange->All,Axes->True]; (* stacked plots with proper y values *)
