Comparison chart
The comparison chart is a line chart that explores the relation between relative and absolute performance of the selected product over time. The vertical axis on the right side shows the relative performance which is represented by the ranking and vertical axis on the left side shows the absolute performance which is represented by actual values of the selected element. The two trend lines can have opposite directions.
For example, if you have three products, A, B, and C, where the revenue and absolute value, of product B is increasing, then the relative ranking of product B could be declining simultaneously. In this case, product A or C is more successful.
