In Bar graph,
We made a table to a bar graph
Class |
5 th |
6 th |
7 th |
8 th |
9 th |
Number of girls | 30 | 35 | 20 | 25 | 40 |
Class |
5 th |
6 th |
7 th |
8 th |
9 th |
Number of girls | 30 | 35 | 20 | 25 | 40 |
But,
What if we have data like this
Class |
5 th |
6 th |
7 th |
8 th |
9 th |
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
Class |
5 th |
6 th |
7 th |
8 th |
9 th |
Number of girls | 30 | 35 | 20 | 25 | 40 |
Number of boys | 20 | 40 | 25 | 35 | 20 |
Let’s take another example
Suppose population of India & China are
Years |
1951 |
1961 |
1971 |
1981 |
1991 |
2001 |
Population (in crores) |
36 |
44 |
54 |
68 |
84 |
102 |
Here, population is from 36 to 110
we draw graph from 0 to 110 with gap of 10
Years |
1951 |
1961 |
1971 |
1981 |
1991 |
2001 |
Population of India (in crores) |
36 |
44 |
54 |
68 |
84 |
102 |
Population of China (in crores) |
58 |
64 |
70 |
90 |
100 |
110 |
