histogram without vertical lines

Question

When I create a histogram, it looks a lot like this:

set.seed(1)
x <- 1:100
y <- x + rnorm(50)
y=round(y)
hist(y)

Is there a way to make a histogram look a bit like this? I can only get a histogram with bins, which I don't need for my plot.

I don't want the black bins, I actually only want the blue, green and red lines. Can stackoverflow point me in the right direction?

are the blue, red, and green lines density curves? Some sample data would help as well. – Verbiage

Yeah, all of them are density curves – Progression

Answer 1

Put your histogram in an object, and use type="s" to get the stepwise plot :

x <- rnorm(1000)
y <- hist(x)
plot(y$breaks,
      c(y$counts,0)
   ,type="s",col="blue")

gives :

That's exactly what i'm looking for (now let's try this out) – Progression

Answer 2

If you want to keep the (eventual) coloring of you histogram, you can deactivate the border and add it yourself on top.

x <- rnorm(1000)
h <- hist(x, col="royalblue", border=NA, freq = T)

lines(rep(h$breaks, each=2)[-c(1,2*length(h$breaks))], 
      rep(h$counts, each=2), lwd=2)

# replace h$counts by h$density if freq=F
