I suspect move_base is publishing to /cmd_vel, but in rqt_graph it looks like you've asked it to hide unused topics; that is probably why you aren't seeing it. I suggest you uncheck "Dead sinks" and "Leaf topics"

I suspect your robot is not moving because you do not have a subscriber to cmd_vel to implement motion based on cmd_vel.

Hi, could you uncheck everything but unreachable and params and reupload the image?
