Bar graph showing the percentage of books sold In a week days.
Steps of construction:
1. Draw two mutually perpendicular lines on a graph sheet – one horizontal (X-axis) and one vertical (Y-axis).
2. Mark name of the day on the Yaxis and the number of books sold on the X-axis.
3. Take the 10 as scale on the X-axis i.e., 1cm = 5 books.
On Monday = 65 ÷ 5 = 13 cm
On Wednesday = 30 ÷ 5 = 6 cm
On Friday = 70 ÷ 5 = 14 cm
On Tuesday = 40 ÷ 5 = 8 cm
On Thursday = 50 ÷ 5 = 10 cm
On Saturday = 20 ÷ 5 = 4 cm
4. Calculate the lengths of the bars by dividing the number of books with the scale.
5. Draw rectangular horizontal bars of same width (1cm) on the Y-axis with their calculated lengths. Hence, required horizontal bar graph was constructed.
