In my opinion, the most effective graph for conveying the information is the graph c. First of all, we can read the value of series easier with the 2-D clustered column. Therefore, we can compare effectively between 4 quarters.
However, the least effective is the graph b. So the graph b uses the 2-D stacked column. It makes me confused to compare the value in the 4 quarters. Additionally, it is so hard for me to read the value between series 1 and series 2.
To make the graph c better, we should convert the number values to the percentage values. By doing this, we can compare the value easier and more effective.
I think you did a good job here. However, the exercise does not require explaination about how you choose graph c and b. Thus, you dont need to include ones.
Trả lờiXóaBeside, the percentage idea is great, but i think we should not remove the number value. We should put include both of them.( Hai Nam, 09ece)
