Lines connect the same items across columns and indicate the agreement (or disagreement) between developers and reporters on that particular item. Figure 24-3 shows that the results match only for the top three items and the last one. In between there are many disagreements, and the most notable ones are for stack traces, test cases, code examples, product, and operating system.
