Plant	Bhilai	Durgapur	Rourkela	Bokaro
Production (In thousand tonnes)	160	80	200	150

Construct a bar graph to represent the above data on a graph paper by using the scale 1 big division = 20 thousand tonnes.

Answer 1

1. Mark the horizontal axis OX as “Name of the Steel Plant” and the vertical axis OY as “Production (in thousand tonnes)”.

2. Along the horizontal axis OX, choose bars of uniform (equal) width,with a uniform gap between them.

3. Choose a suitable scale to determine the heights of the bars,according to the space available for the graph.Here, we choose 1 big division to represent 20 thousand tonnes.
