This question is pretty vague.  Please read the posting guide.

If you want to rescale the y-axis you could do something like:

 > set.seed(333) # Only half evil.
 > x <- rnorm(300)
 > h <- hist(x,plot=FALSE)
 > h$counts <- h$counts*42
 > plot(h,ylab="Rescaled counts")

If you want to rescale the x-axis, see the posting by Stephan Devriese.
