Hi,

Does anybody encounter the same problem when we overlap histogram and density 
    that the density line seem to shift to the right a little bit?
     
    If you do have the same problem, what should we do to correct that?
     
    Thank you.
     
    par(mar=c(4,4,2,1.2),oma=c(0,0,0,0))
    hist(datobs,prob=TRUE, main ="Volume of a catchment from four 
    stations",col="yellowgreen", cex.axis=1,
    xlab="rainfall",ylab="Relative frequency", ylim= c(0,.003), xlim=c(0,1200))
    lines(density(dd), lwd=3,col="red")
    
#legend("topright",c("observed","generated"),lty=c(0,1),fill=c("blue",""),bty="n")

    legend("topright", legend = c("observed","generated"),
           col = c("yellowgreen", "red"), pch=c(15,NA), lty = c(0, 1), 
           lwd=c(0,3),bty="n", pt.cex=2)
    box()

Thank you.
