Unknown item shown in rqt_graph
In my rqt_graph shown below, the namespace path_modification
has an oval titled color
in the namespace. What is this?
I've looked at rostopic list
and it's neither a topic nor a service running on the network. I've googled around, but I can only find information about the display color of a node in rqt_graph
, not an item titled "color" in rqt_graph
.
rosnode info path_modification
returns:
Node [/path_modification]
Publications:
* /rosout [rosgraph_msgs/Log]
Subscriptions: None
Services:
* /path_modification
* /path_modification/get_loggers
* /path_modification/set_logger_level
contacting node http://127.0.0.1:44616/ ...
Pid: 11250
Connections:
* topic: /rosout
* to: /rosout
* direction: outbound
* transport: TCPROS
I don't see anything related to "color" at all in that output. I don't think rqt_graph
shows rosparams, but I checked rosparam list
and I don't see "color" in there either. The output of rosnode list
is:
/path_modification
/ramp_planner
/ramp_sensing
/rosout
/trajectory_evaluation
/trajectory_generator
/trajectory_view
So it doesn't seem to be a node either. If anyone knows what this is, please let me know. Any help is appreciated.
