in the rqt_plot part of understandingTopic toturial http://wiki.ros.org/ROS/Tutorials/Und...
the topic is
/turtle1/pose/x
/turtle1/pose/y
/turtle1/pose/theta
but I can only find the topic
/turtle1/pose/
using command
rostopic list
(and rqt_plot doesn't work when only fill /turtle1/pose/ in the textbox)
where can I find the x/y/theta?
you must use it in this form
rqt_plot /topic1/field1
To graph multiple fields of a message:
rqt_plot /topic1/field1:field2:field3
To graph the data all on the same plot:
$ rqt_plot /topic1/field1,/topic2/field2
use "$rosmsg show msg_name" or use "$rostopic echo topic_name " to see diffrent fields of msg
