# `sphinx.ext.inheritance_diagram` – Include inheritance diagrams

New in version 0.6.

This extension allows you to include inheritance diagrams, rendered via the `Graphviz extension`.

It adds this directive:

`.. inheritance-diagram::`

  This directive has one or more arguments, each giving a module or class name. Class names can be unqualified; in that case they are taken to exist in the currently described module (see `py:module`).

  For each given class, and each class in each given module, the base classes are determined. Then, from all classes and their base classes, a graph is generated which is then rendered via the graphviz extension to a directed graph.

  This directive supports an option called `parts` that, if given, must be an integer, advising the directive to remove that many parts of module names from the displayed names. (For example, if all your class names start with `lib.`, you can give `:parts: 1` to remove that prefix from the displayed node names.)

  It also supports a `private-bases` flag option; if given, private base classes (those whose name starts with `_`) will be included.

  Changed in version 1.1: Added `private-bases` option; previously, all bases were always included.

New config values are:

`inheritance_graph_attrs`

  A dictionary of graphviz graph attributes for inheritance diagrams.

  For example:

      inheritance_graph_attrs = dict(rankdir="LR", size='"6.0, 8.0"',
                                     fontsize=14, ratio='compress')

`inheritance_node_attrs`

  A dictionary of graphviz node attributes for inheritance diagrams.

  For example:

      inheritance_node_attrs = dict(shape='ellipse', fontsize=14, height=0.75,
                                    color='dodgerblue1', style='filled')

`inheritance_edge_attrs`

  A dictionary of graphviz edge attributes for inheritance diagrams.
