Hello, I'm using ROS kinetic on Ubuntu 16.04.

My work has something to do with social navigation through a method kind of machine learning, and I've already gotten some results saying the agent can properly get to the destination without collision.

But I only have reward-plottings during each training, so I think it may not be enough to persuade my supervisors.

I also think it would be more helpful if I suggest the entire trajectory with them.

The agent should be operated with Gazebo simulator and RViZ, so I'm planning to mark them on the RViZ sheet.

In this case, how can I show the trajectories?

In my understanding, it seems that I can just plot some marks on the position of the agent at every timestamp.

Unfortunately, being not familiar with these Gazebo or RViZ, I don't have any ideas what should I do.

And also I'm not sure whether my way would go well; that is I might be wrong.

So if anyone is familiar with SLAM or the navigation of mobile agents, I think they've ever done this kind of marking work on the agent's trajectories.

Would you please give me helpful advice?

Thanks :)

You might like to look at LINE_STRIP .
There are other marker types as well.
