But,

What if we have data like this

Number of girls 30 35 20 25 40
Number of boys 20 40 25 35 20

Here, we make a double bar graph.

 

Since number of students are from 20 to 40

We draw bar graph from 0 to 45

  with a gap of 5

Let’s take another example

 

Suppose population of India & China are

Population

102

Here, population is from 36 to 110

  we draw graph from 0 to 110 with gap of 10
