As you’ve probably figured out, this graph is not available in SonarQube. What’s available instead is a series of bubble charts showing Risk, Reliability, &etc
More generally, what we make very visible is the QG status, because that’s what we really feel you should be paying attention to
And if the concern is really which projects are adding issues, this is the way to go: set up a default Quality Gate that’s focused on New Code. In fact, the Built-in Sonar way Quality Profile focuses exclusively on New Code
And if you have a Quality Gate that focuses on new code, then you don’t really need fancy graphs to know which projects are doing well, you just look at which ones are releasable (passing the Quality Gate) and which ones aren’t.
With regard to fixing old issues, here’s why we feel that’s not really where the emphasis should be: https://docs.sonarqube.org/display/SONAR/Fixing+the+Water+Leak
