That is quite different from your example. I believe overlay of density curve over histogram was discussed several times e.g. http://tolstoy.newcastle.edu.au/R/e4/help/08/06/14198.html > > And a newY() (or par(newY=TRUE) command would enable exactly this. This is something beyond my knowledge and it could be that this need some deep redefining in base R graphics.
