Hi, I drew the frequency histogram using Gnuplot by Commands.

gnuplot> rounded(x)=0.1*(floor(x/0.1)+0.5)
gnuplot> plot"hist1.txt" u (rounded($1)):(1) smooth frequency with boxes

"hist1.txt"--> File
5
2
3
2
3
1
2
1
5
5

Here I got a histogram in which x-axis is "entry" of hist1.txt file and y-axis there is frequency.  But folks I'm having two difficulties with these.

1. I want to get a histogram with probability density rather than frequency. Means my histo box should show frequency/total no. of points. 

2 How to set/change the width of the histogram.

thank you for your reply!!
