Package Summary

Released Continuous integration Documented

rqt_graph provides a GUI plugin for visualizing the ROS computation graph.
Its components are made generic so that other packages where you want to achieve graph representation can depend upon this pkg (use rqt_dep to find out the pkgs that depend. rqt_dep itself depends on rqt_graph too).

Overview

launch top window

rqt_graph is the successor of rxgraph.

Topic statistics

New in ROS indigo

roscpp and rospy can measure certain statistics for every topic connection (see Topics for more details. This has to be enabled beforehand through:

$ rosparam set enable_statistics true

After that, rqt_graph will automatically annotate the ROS graph with statistics information.

Note: rqt_graph currently does not automatically update the statistics annotations. You have to hit the Refresh button to update them.

Example

This is an example of rqt_graph with statistics measurement enabled:

ROS graph with statistics annotations

Legend:

  • "5.0 Hz" indicates the observed publish frequency.
  • // "110.0ms" indicates the average age of the message (might be very large when replaying bag files without simtime).
  • line color: red marks a high avery age, green a young age. The limits are normed to the ages observed in the ROS graph.
  • line thickness: A thick line means the connection has a large throughput in Bytes/s (e.g. an unfiltered PointCloud).
