Drawing a bar graph:

1) Information about the plants in a nursery is given here. Show it in a bar graph.

Names of Plants Rose Mogra

Hibiscus

Chrysanthemum

Number of Plants 70 50 45 80

Solution:

Take a graph paper.

  1. Draw the X and Y axes, and mark O, their point of intersection. In the centre, write the title ‘Types and number of plants’.

  2. Write the names of the plants on the X-axis at equal distances.

  3. The number of plants is divisible by 5. So, take the scale 0.5 cm = 5 plants, that is, 1cm = 10 plants on the Y-axis as it can be easily shown on the graph paper. Write the scale in the top right-hand corner.

  4. Draw a bar of the appropriate height above the name of each plant on the X-axis.

2) The following table shows the monthly expenditure of Imran’s family on various items.

Items

Expenditure (in Rs.)

House rent 1200
Food 1400
Education 800
Electricity 400
Transport 600
Miscellaneous 1000

To represent this data in the form of a bar diagram, here are the steps.

(a) Draw two perpendicular lines, one vertical and one horizontal.

(b) Along the horizontal line, mark the ‘items’ and along the vertical line, mark the corresponding expenditure.

(c) Take bars of the same width keeping the uniform gap between them.

(d) Choose a suitable scale along the vertical line. Let 1 unit length = 200 and then mark the corresponding values.
Calculate the heights of the bars for various items as shown below.

House rent: 1200 ÷ 200 = 6 units

Food: 1400 ÷ 200 = 7 units

Education: 800 ÷ 200 = 4 units

Electricity: 400 ÷ 200 = 2 units

Transport: 600 ÷ 200 = 3 units

Miscellaneous: 1000 ÷ 200 = 5 units.
