Graph LegendThis page explains how to interpret the graphs that are generated by doxygen.
Consider the following example:  
class Invisible { };
 class Truncated :  public Invisible { };
 class Undocumented { };
 class PublicBase :  public Truncated { };
 template< class T>  class Templ { };
 class ProtectedBase { };
 class PrivateBase { };
 class Used { };
 class Inherited :  public PublicBase,
                   protected ProtectedBase,
                   private PrivateBase,
                   public Undocumented
                  public Templ<int>
{
   private:
     Used *m_usedClass;
};
   If the MAX_DOT_GRAPH_HEIGHT tag in the configuration file is set to 240 this will result in the following graph:
 
 
The boxes in the above graph have the following meaning:  
- 
A filled black box represents the struct or class for which the graph is generated. 
 
- 
A box with a black border denotes a documented struct or class. 
 
- 
A box with a grey border denotes an undocumented struct or class. 
 
- 
A box with a red border denotes a documented struct or class forwhich not all inheritance/containment relations are shown. A graph is truncated if it does not fit within the specified boundaries. 
 
 
The arrows have the following meaning: 
- 
A dark blue arrow is used to visualize a public inheritance relation between two classes. 
 
- 
A dark green arrow is used for protected inheritance. 
 
- 
A dark red arrow is used for private inheritance. 
 
- 
A purple dashed arrow is used if a class is contained or used by another class. The arrow is labeled with the variable(s) through which the pointed class or struct is accessible. 
 
- 
A yellow dashed arrow denotes a relation between a template instance and the template class it was instantiated from. The arrow is labeled with the template parameters of the instance.
