You can make rviz "remember" more by increasing the decay time in the laser
display.

Note that you are not actually mapping in the sense of doing SLAM.  You're
just accumulating scans.  It looks like a coherent map because stage isn't
adding any noise to the laser or odometry data.  The intent of the tutorial
is simply to demonstrate that stage is producing data.

in the rviz the past images gets erased as new places are discovered. is
this normal. i hope u understand what i mean.
when the robot starts from point say "A" and it moves and discovers more and
more places in the map the previous places that it had already discovered(in
rviz) gets erased. i think its due to limited buffer.
