Actually, I want to get this plot:- https://i.ibb.co/NrzdzcN/i-need-this.png
I think this plot is w.r.to density(y-axis) 
But using density I'm getting this plot https://i.ibb.co/TRR2LYN/Plot-kden.png
I want to replot this plot with a different width of each histo bars.  My basic problem is I still don't know how to set each histo bar width.  What does mean by kdensity. Please share me to solve this mystery (For me).
I think you got it my problem.
