Live Scan from RPLidar not in line with SLAM Map

edit

Hi there, I am working on a robot that uses the SLAM algorithm to map out its surrounding, using Hector SLAM. It is able to generate a live map of my surroundings, however, i cannot seem to get the laser scan to work together with the map by showing its live movement as it goes through the map (aka as I move, the map gets bigger and increases in size, my pose moves, but the laser scan stays at the centre. Can anyone help? My hectorslam launch file is as shown
