# Graph Legend

This page explains how to interpret the graphs that are generated by doxygen.

Consider the following example:

    /*! Invisible class because of truncation */
    class Invisible { };

    /*! Truncated class, inheritance relation is hidden */
    class Truncated : public Invisible { };

    /* Class not documented with doxygen comments */
    class Undocumented { };

    /*! Class that is inherited using public inheritance */
    class PublicBase : public Truncated { };

    /*! A template class */
    template<class T> class Templ { };

    /*! Class that is inherited using protected inheritance */
    class ProtectedBase { };

    /*! Class that is inherited using private inheritance */
    class PrivateBase { };

    /*! Class that is used by the Inherited class */
    class Used { };

    /*! Super class that inherits a number of other classes */
    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.
