Explanation:

A Pareto chart is a diagram of bars and line graph, uses the descending bars to represent the individual items or factors, while the lines represents the cumulative total of the individual items. It is used to point out the most important item on the graph and sometimes, the most common cause of a problem.

The XY chart is a graph that shows the relationship of two items using scattered plot graph. This scattered plot uses thick dots to mark the intersection line between items.
