    Oh, I had not thought of it in those terms.  It does make sense now.

     Why not just plot the two histograms on the same scale in a 2 panel plot?

   I think OP request was "for comparison". Two panels may do, but why not a
   barplot of the histograms in the same panel ?
   barplot( rbind(
   hist(rbeta(30,2,4),breaks=seq(0,1,.1),plot=F)$counts,
   hist(rbeta(30,6,8),breaks=seq(0,1,.1),plot=F)$counts),
   beside=T)
   see str(hist(yourdata)) or ?hist
