How will I draw a double bar graph on weight and age of a person with a suitable scale ? Please give me a sample of it....

The double bar graph shown above represents the weight of a person in kilogram and age of the person in years.

For example, in 1981, age of a person is 40 years while his weight is 65 kg.

Similarly, in 1991, age of a person is 50 years while his weight reduced to 60 kg.

In this manner you can show the age and weight of a person on double bar graph.

Hope you get it!!
