This bar graph shows the maximum temperatures in degrees Celsius in different cities
on a certain day in February. Observe the graph and answer the questions.
1. What data is shown on the vertical and the horizontal lines?
2. Which city had the highest temperature?
3. Which cities had equal maximum temperatures?
4. Which cities had a maximum temperature of 30°C?
5. What is the difference between the maximum temperatures of Panchgani and
Chandrapur?
SOLUTION
1. Temperature is shown on the vertical line (Y-axis) and different cities are shown
on the horizontal line (X-axis).
2. Chandrapur had the highest temperature (35°C) as the height of the bar
corresponding to the city Chandrapur is maximum.
