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 subjects at the points that are taken at a uniform gap.
Step:3-Choose the scale:
1 big division=10 marks
1 small division=1 mark.
Step:4-Draw bars of equal width on the x−axis.The difference between the two bars should also be the same.
