@gvdhorn told you that plotting tf-frames as it is not possible to access your end-effector pose with rqt as it's not published. Write a node that uses tf to get the pose and publish it on a topic that you then visualize in rqt_plot.

start with a tf client http://wiki.ros.org/tf/TfUsingPython and publish your coordinates

@NEngelhard: ROS Answers is a forum for beginners, so your reaction might be a bit harsh.

@zakizadeh: please take a look at the link @NEngelhard posted, especially section 2.1. But note that the pkgs I linked in #q252572 already do this.

If you can't get it to work, please update #q252572.

It's #q252572. Not #q3252572 (note the extra 3).
