[R] Problem with plot histogram

[danielepippo]

Hi R-users,
    
    I'm trying to built a plot of two series of data, but thees series
result "superimposed". The R-code is like this:

goal <- c(125, 143, 81, 26, 2, 3) 
numgoal <- 0:5 
lambda <- sum(goal*numgoal)/sum(goal) 
plot(numgoal, goal, type="h") 
x <- 0:5
y<-dpois(x, lambda)  
att<-y*380 
lines(x,att, type="h", col="red") 
legend(x="topright", legend=c("Osservate", "Attese"), col=c("black","red"),
ncol=1, lty=1, lwd=3,
 inset=c(0.01, 0.02), bg="white")


How can I draw the two lines one near other?

Thanks a lot to everyone
