Thank you Prof. Karl.
For density histogram, I used smooth density. i.e.
gnuplot> plot"hist1.txt" u (bin($1,width)):(0.1) smooth kden  w boxes t"".
Gives me desired shape of the density histogram.

But Sir each histogram has its box shape I didn't understand how to set bin_width of the histogram using:
gnuplot> width=0.7
gnuplot> bin(x,width)=width*floor(x/width)

I found no result regarding fnormal.
