NEngelhard told me: " you need to use a tf listener to get the pose and republish these values so that rqt_plot is able to plot them. "

but I do not know what to do. can any body write tf listener for RRRBot robot ??

Here is a full example (just google "tf listener": tf listener

Just replace the frames by the ones you need (Most probably something like 'world' and 'link3' for your robot) and publish the position.
