Dependency Graph

• This diagram represents the Graph of Dependencies between the projects of your application.
• This static diagram can be useful but it is just a coarse view of your application architecture.
• It is recommended to use the NDepend interactive Dependency Graph and interactive Dependency Matrix found in the NDepend UI for an in-depth exploration of the actual architecture of your code.

Dependency Matrix

• This diagram represents the DSM (Dependency Structure Matrix) between the projects of your application.
• The Dependency Matrix is a compact way to represent and navigate across dependencies between components.
• The number on cells of the Dependency Matrix included in the report, represent the number of types involved in the coupling
• It is recommended to use the NDepend interactive Dependency Matrix and interactive Dependency Graph found in the NDepend UI for an in-depth exploration of the actual architecture of your code.

Visualizing Code Metrics through Treemaping

• In this Metric View, the code base is represented through a Treemap.
• Treemapping is a method for displaying tree-structured data by using nested rectangles.
• In the present treemap, each rectangle represents a method and the area of a rectangle is proportional to the number of lines of code of the corresponding method.
• It is recommended to use the NDepend interactive Metric View found in the NDepend UI for an in-depth code metrics exploration.

With the Online documentation, understand how Treemaping can help you see patterns in your code base, that would be hard to spot with other ways.

Abstractness versus Instability Diagram

The Abstractness versus Instability Diagram helps to detect which projects are potentially painful to maintain (i.e concrete and stable) and which projects are potentially useless (i.e abstract and instable).

• Abstractness: If a project contains many abstract types (i.e interfaces and abstract classes) and few concrete types, it is considered as abstract.
  
• Instability: A project is considered stable if its types are used by a lot of types from other projects. In this context stable means painful to modify.

For beginners: Where to start

• The Issues tab makes it easy to identify the source files with most issues and most technical debt.
• Write clean code from now on: The first analysis result of your project is considered as the baseline. Continue your development and further analysis results will be compared against the baseline. In all tabs new issues introduced on new and refactored classes will be highlighted. This will be the issues to fix first.
• Import test coverage data to assess possible improvements in your testing strategy .
• Watch the series of 4mn videos about various NDepend features.
• Discover the most typical use-cases.
• In addition to the NDepend report, use the interactive UI through the standalone executable VisualNDepend.exe, or through the Visual Studio NDepend extension. With the interactive UI, browse more detailed data and have Rules checking updated each time the code is modified and recompiled.
• The baseline, the analysis execution and the report options settings are customizable through the interactive UI, in the panel Project Properties.

Code queries and rules results are truncated to list a maximum of 20 code elements in this report

• To enable or disable this setting, there is a tickbox labelled Don't show more than 20 matched items for a Rule violated in the NDepend Project Properties panel > Report tab > Avoid too big report for large code base section
• This setting is enabled by default to avoid to have too large reports when analyzing large code bases.

Does this report gets too large?

• There is a setting enabled by default to avoid to have too large reports when analyzing large code bases.
• To enable or disable this setting, there is a tick-box labelled Don't show more than 100 matched items for a Rule violated in the NDepend Project Properties panel > Report tab > Avoid too big report for large code base section
