The gcov view is simlar to the gprof view but keep in mind that you're looking at code coverage and not necessarily performance or timing information (though there is a relationship...code not executed is performing quite well ! ). Also note that multiple executions will accumulate values in the gcov output files until they are removed or truncated to zero-length (2nd run to demonstrate this).
Selecting (double click) a source code line from either the gcov or gprof view and you'll see the file and routine highlighted in the cdt c/c++ perspective.
