Data Handling: Choice of Graphs by Xavier Toh

1) The line graph is inappropriate.
2) Line graphs are used to know the amount of change of something instead of  how much there is of something.
3)The three other graphs show the same number of symbols like the sun as depicted on the weather map. For example, the weathers are all sunny, so the pie chart is filled with yellow, the colour representing the sun.

  1. Correct.
    You have rightly pointed out that line graph tracks changes over time.
