Given, The temperature in the morning and evening of the first week of March. Days Monday Tuesday Wednesday Thursday Friday Saturday Sunday Temperature in the morning 30 °C 21 °C 17 °C 22 °C 21 °C 17 °C 12 °C Temperature in the evening 22 °C 15 °C 20 °C 22 °C 15 °C 12 °C 8 °C To draw a double bar graph first we need to choose the scale such that the maximum temperature 30 °C and the minimum temperature 8 °C are included. Use equal division of increment of 2 °C . So, all bar lie between 0 °C and 32 °C . We can draw the double 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 days at the points that are taken at a uniform gap. Step 3.- Choose the scale: 1 big division = 2 °C 1 small division = 0 . 2 °C Step 4.-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:

The height of some tall structures in the world is given as follows. Structure Country Height in Metres Empire State Building USA 449 Delhi TV Tower India 234 Telecom Tower Great Britain 204 Eiffel Tower France 321 Represent the above data by drawing a bar graph with appropriate scale.

Given, The height of some tall structures in the world is given as follows. Structure Country Height in Metres Empire State Building USA 449 Delhi TV Tower India 234 Telecom Tower Great Britain 204 Eiffel Tower France 321 To draw a bar graph first we need to choose the scale such that the maximum value 449 and the minimum value 204 are included. So, all bar lie between 0 and 500 . 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 name of the structure and city at the points that are taken at a uniform gap. Step 3.- Choose the scale: 1 unit = 100 Metres Step 4.- To draw this bar graph we will take the approximate value of all the heights so that we can easily show them on graph. For example: 449 ≈ 500 , 234 ≈ 230 , 204 ≈ 200 , 321 ≈ 320 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:

Use equal division of increment of 200 . So, all bar lie between 0 and 900 . We can draw the double 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 month at the points that are taken at a uniform gap. Step 3.- Choose the scale: 1 big division = 200 books 1 small division = 20 books Step 4.-Draw the bars of equal width on the x- axis. The difference between the two bars should also be the same.
