If you are running an application instrumented with PureCoverage, this button is active when the application has saved its coverage data. Click the button to display the PureCoverage Viewer with the accumulated results saved in the coverage data file.
The show coverage feature is implemented by the script pure_invoke_purecov in the Purify installation directory. You can copy and customize this script, and add its location to your $PATH so that the Viewer can find your customized copy.
