We can draw the bar graph by following the given steps:
Step 1- On a graph paper, draw a horizontal line OX as x-axis and vertical line OY as y-axis.
Step 2- Along OX, write the names of the months at the points taken at a uniform gap.
Step 3- Choose the scale:
1 big division = 5 cm
2 small divisions = 1 cm
Step 4- Heights of the various bars:
June = 50 small divisions = 5 big divisions
July = 60 small divisions = 6 big divisions
August = 80 small divisions = 8 big divisions
September = 40 small divisions = 4 big divisions
October = 20 small divisions = 2 big divisions
November = 10 small divisions = 1 big division
Step 5- Draw bars of equal width on the x-axis. The difference between the two bars should also be the same.
We get the following bar graph:
