Answer: Line Graph
Given:
Two time periods or points of comparison and want to quickly show relative increases and decreases.
Answer:
Line Graphs helps us to represent data that continuously varies over time and it can also be effectively used to re present relative increase and decrease between data within a span of time or period.
Using a line graph, multiple lines can be depicted in a single plot such that they can compared with one another. (the lines must be given in different colours to differentiate among each other).
