The XRadar has since the last release got some important enhancements for bringing all views closer together. You can now navigate from system architecture to code, from the current build to the systems development in time. All these are found on system, module, package, class and method scope.
In addition comes the existing plethora of measurements it makes such as package metrics and dependencies, code size and complexity, coding violations and code-style violations, unit test metrics, duplications and code coverage. All data is as always presented in a browsable, graphical and consistant form.
See http://xradar.sourceforge.net for the teasers.
