rostopic list
Hy!:) If I want to visualize a topic, but if I type in a rostopic list, I have few topics, do I have to first subscribe to the topic I want and then visualize? I want to clarify this question because of my initial knowledge.
Elaborate "visualize". Are you perhaps looking for rostopic echo?
As I know, I prefer to use the rostopic pub command. I have bag files and want to visualize it for them
Can you maybe elaborate more or give a short example or what you have, please? Still hard to understand what you are trying to do.
I want to visualize the topic of a bag file, maybe you can help with that?
You are not providing more details. I can only suggest what abhishek47kashyap already did:
