Trend charts are displayed in the NDepend dashboard, in the NDepend report and in the Azure DevOps hub. Some trend charts are follow the trend of:

  • Lines of code
  • Technical-debt expressed in human-time to fix issues
  • Number of issues

  • Code coverage ratio
  • Max and average values for various code quality metrics like method's Cyclomatic Complexity
