Hi there,

I'm noticing some incoherent pose output when replaying a rosbag on the turtlesim. I run those nodes:

/rosout
/rqt_gui_py_node_8247
/teleop_turtle
/turtlesim

Then I record a rosbag with and then hit some keys to give the turtle a constant speed

$ rosbag record -a

Finally I replay it with

 $ rosbag play 2013-09-27-18-49-00.bag

The Turtlesim behaves fine, but the matplot shows some weird results as you can see in this screenshot: image description

Any idea why it is behaving like that?

Cheers,

Stanislas

Interesting. Is it possible for you to share the `.bag` file with us? If so just put it wherever we can access and tell the URL. Thanks.
