I'm trying to display the trail of my robot in RViz. I know that it's possible by publishing a visualization_msgs/Marker something like in this tutorial: [Markers: Points and Lines (C++)](http://wiki.ros.org/rviz/Tutorials/Markers%3A%20Points%20and%20Lines). However, at first I'd like to know if it's possible to do it easier way using display type RobotModel -> Links -> base_link -> show trail. Yes, it draws a path of my robot but only a small part of it - after a few seconds of driving the beginning is 'erased'. Is it possible to make the history/lifetime (not sure how to exactly call it) of my trail longer?
