उत्तर
In order to construct a bar graph representing the above data, we follow the following steps:
Step I: Take a graph paper and draw two mutually perpendicular lines OX and OY. Let OX as the horizontal axis and OY as the vertical axis.
Step II: Along OX, mark type of the plant and along OY, mark number of plants.
Step III: Choose a suitable scale to determine the heights of the bars, according to the availability of space. Here, we choose 1 unit length represents 10 plants.
Step IV: Calculate the height of various bars as follows
| Type of the plants | Height of bars |
| Herb | `50/10` = 5 units |
| Shrub | `60/10` = 6 units |
| Creeper | `20/10` = 2 units |
| Climber | `45/10` = 4.5 units |
| Tree | `95/10` = 9.5 units |
Hence, the required bar graph for the given data is shown below
Scale: 1 unit length = 10 plants
