eLearning Lesson 1 Task 1: Choice of Graphs

Among the 4 graphs (Line Graph, Bar Graphs, Pictograms, Pie Charts), identify ONE graph that is NOT an appropriate choice to represent the information?

I think the Line Graph is inappropriate to represent the information on the interactive lab. This is because the horizontal axis's data is supposed to be constantly increasing. And thus the information on the horizontal axis should be a number. In this case we are calculating the weather and thus the line graph is inappropriate. 
Bar graphs and pictograms are both appropriate as they are both suited to represent these kind of pictorial information. The do not have any rules that subject them to increase or decrease the information on any of the axes. Pie charts can also help to represent this data as pie charts make use of the percentages of the data.
