Graphs
|
||||
======
|
||||
|
||||
This page has a parameter that sets the location of a Web Dot
|
||||
server, or of the Web Dot binary on the local system, that is used
|
||||
to generate dependency graphs. Web Dot is a CGI program that creates
|
||||
images from :file:`.dot` graphic description files. If
|
||||
no Web Dot server or binary is specified, then dependency graphs will
|
||||
be disabled.
|
||||
Bugzilla can draw graphs of bug dependency relationships, using a tool called
|
||||
:file:`dot` (from the `GraphViz project <http://graphviz.org/>`_) or a web
|
||||
service called Web Dot. This page allows you to set the location of the binary
|
||||
or service. If no Web Dot server or binary is specified, then dependency
|
||||
graphs will be disabled.
|
||||
|
||||
webdotbase
|
||||
It is possible to show graphs of dependent bugs. You may set this parameter to any of the following:
|
||||
You may set this parameter to any of the following:
|
||||
|
||||
* A complete file path to :command:`dot` (part of GraphViz) will generate the graphs locally.
|
||||
* A URL prefix pointing to an installation of the webdot package will generate the graphs remotely.
|
||||
* A blank value will disable dependency graphing.
|
||||
* A complete file path to :command:`dot` (part of GraphViz), which will
|
||||
generate the graphs locally.
|
||||
* A URL prefix pointing to an installation of the webdot package, which
|
||||
will generate the graphs remotely.
|
||||
* A blank value, which will disable dependency graphing.
|
||||
|
||||
The default value is a publicly-accessible webdot server. If you change this value, make certain that the webdot server can read files from your webdot directory. On Apache you do this by editing the :file:`.htaccess` file, for other systems the needed measures may vary. You can run :command:`checksetup.pl` to recreate the :file:`.htaccess` file if it has been lost.
|
||||
The default value is blank. We recommend using a local install of
|
||||
:file:`dot`. If you change this value to a web service, make certain that
|
||||
the webdot server can read files from your webdot directory. On Apache
|
||||
you do this by editing the :file:`.htaccess` file; for other systems the
|
||||
needed measures may vary. You can run :command:`checksetup.pl` to
|
||||
recreate the :file:`.htaccess` file if it has been lost.
|
||||
|
||||
font_file
|
||||
You can specify the full path to a TrueType font file which will be used to display text (labels, legends, ...) in charts and graphical reports. To support as many languages as possible, we recommend to specify a TrueType font such as Unifont which supports all printable characters in the Basic Multilingual Plane. If you leave this parameter empty, a default font will be used, but its support is limited to English characters only and so other characters will be displayed incorrectly.
