Suppose I have some people and they are of different weight, e.g.
weight in Kq: 40-45 45-50 50-55 55-60 60-65
No. of Persons: 4 12 13 6 5
I want to represent the weight on x-axis and No. of persons on y-axis. This will tell us that there are 4 persons whose weight lies within 40-45 and 12 persons whose weight lies in the interval 45-50 kilo and so on. How can we do that?
