rxgraph

Usage

Usage: rxgraph [options]

Options:
  -h, --help            show this help message and exit
  -o DOTFILE, --dot=DOTFILE
                        ouput graph as graphviz dot file

• -o DOTFILE, --dot=DOTFILE

  • rxgraph can save a GraphViz "dot" file of the ROS graph. This is useful for producing documentation of your online system.

New in ROS 1.1

• --nodens=NAMESPACE

  • Only display nodes in specified namespace.

  --topicns=NAMESPACE

  • Only display topics in specified namespace.

Removed in ROS 1.1

The -q and -t options were removed from the command-line and replaced with 'quiet' and 'All topics' check-boxes in the toolbar.

The quiet option removes the following nodes:

['/diag_agg', '/runtime_logger', '/pr2_dashboard', '/rviz', 
'/rosout', '/cpu_monitor', '/monitor','/hd_monitor', '/rxloggerlevel', '/clock']

Usually, topics are marked with edges and nodes by ellipses. The 'All topics' option makes the topics appear as rectangles. It also makes those topics visible which have either no publishers or no subscribers.
