A bar chart is displayed showing the number of adults who said 鈥測es鈥� and 鈥渘o鈥� to a question in a survey.

In a bar graph, it is very important for the vertical scale to begin from 0.The lengths of the bar are drawn according to the numbers on the vertical scale. Moreover, the length of the bar represents the frequency of the corresponding category.

If the vertical scale does not begin from 0, the difference in the frequencies of the categories is greatly exaggerated.

Here, the vertical scale begins from 800 and not 0. This results in a false impression in the minds of the readers that there is a great difference in the number of adults who said 鈥測es鈥� and who said 鈥渘o鈥� when the actual difference is not that large.

Thus, the graph is misleading.
