Thanks for the quick response. But the points I'm trying to superimpose isn't exactly the density of the data. Is there any other way to do it?

I've attached the dataset. What I did was: > hist(data,freq=F) Now I'm trying to superimpose the following points with a line connecting them onto the histogram: x y 100 0.535665393824959 200 0.212744329736556 300 0.0844933242968584 400 0.0335572838043417 500 0.0133275771274986 600 0.00529316714442912 700 0.0021022289461042 800 0.000834919136549392 900 0.000331595645597124 1000 0.000131696193518099 1100 5.2304327929049e-05 1200 2.07731343406939e-05 Basically, the x values correspond to the break points in the histogram. Next I used the command > points(x,y,type="l") But for some reason, the line plot is shifted to the right and doesn't line up with the histogram. Thanks for the help!
