Hi r-users,
 
I try to draw histogram (in terms of probabilty) and superimpose with the gamma pdf. Using this code below I can get the plots BUT the y scale for the density is out of scale.  How do I change the y-axis scale to max 1?  Another thing, how I do draw smooth line rather that points?
 
Nota that my observed data is hume_pos and the fitted data is rgam1.
 
hist(hume_pos,prob=TRUE)
points(density(rgam1), add=TRUE, col="red")
 
Thank you so much for your help.
