Creating an X-Y graph
X-Y graphs are used to show a correlated view of two metrics. This graphing is especially useful for related metrics where the dependency is not very clearly known. Displaying this graph over a period of time can give you a visual representation of the relationship. A good example for online stores may be to correlate a business metric (like $s per hour) with Web server performance. This allows IT groups to justify performance improvements on IT hardware or software.
All such scenarios, where the relationship between two metrics needs to be qualified, are appropriate for X-Y graphs.
