map does not show up on RVIZ while using hector_slam

Hello everyone, i am using RPLIDAR A1 and hector_slam but so for there is no luck, RVIZ will start with nothing and no map in it. Here is the details: from this topic https://github.com/robopeak/rplidar_ros/blob/master/launch/rplidar.launch roslaunch rplidar rplidar.launch and i think it runs fine because i get this SUMMARY ======== PARAMETERS * /rosdistro: kinetic * /rosversion: 1.12.7 * /rplidarNode/angle_compensate: True * /rplidarNode/frame_id: laser * /rplidarNode/inverted: False * /rplidarNode/serial_baudrate: 115200 * /rplidarNode/serial_port: /dev/ttyUSB0 NODES / rplidarNode (rplidar_ros/rplidarNode) auto-starting new master process[master]: started with pid [2876] ROS_MASTER_URI=http://localhost:11311 setting /run_id to 4191033a-ff48-11e7-a91f-08002791f4c4 process[rosout-1]: started with pid [2889] started core service [/rosout] process[rplidarNode-2]: started with pid [2903] RPLIDAR running on ROS package rplidar_ros SDK Version: 1.5.7 RPLIDAR S/N: 4450FBF2C8E49CCFC6E49FF1BA82530D Firmware Ver: 1.20 Hardware Rev: 0 RPLidar health status : 0 then i run roslaunch hector_slam_launch tutorial.launch and i get SUMMARY ======== PARAMETERS * /hector_geotiff_node/draw_background_checkerboard: True * /hector_geotiff_node/draw_free_space_grid: True * /hector_geotiff_node/geotiff_save_period: 0.0 * /hector_geotiff_node/map_file_base_name: hector_slam_map * /hector_geotiff_node/map_file_path: /home/mohamed/cat... * /hector_geotiff_node/plugins: hector_geotiff_pl... * /hector_mapping/advertise_map_service: True * /hector_mapping/base_frame: base_link * /hector_mapping/laser_z_max_value: 1.0 * /hector_mapping/laser_z_min_value: -1.0 * /hector_mapping/map_frame: map * /hector_mapping/map_multi_res_levels: 2 * /hector_mapping/map_resolution: 0.05 * /hector_mapping/map_size: 2048 * /hector_mapping/map_start_x: 0.5 * /hector_mapping/map_start_y: 0.5 * /hector_mapping/map_update_angle_thresh: 0.06 * /hector_mapping/map_update_distance_thresh: 0.4 * /hector_mapping/odom_frame: nav * /hector_mapping/pub_map_odom_transform: True * /hector_mapping/scan_subscriber_queue_size: 5 * /hector_mapping/scan_topic: scan * /hector_mapping/tf_map_scanmatch_transform_frame_name: scanmatcher_frame * /hector_mapping/update_factor_free: 0.4 * /hector_mapping/update_factor_occupied: 0.9 * /hector_mapping/use_tf_pose_start_estimate: False * /hector_mapping/use_tf_scan_transformation: True * /hector_trajectory_server/source_frame_name: scanmatcher_frame * /hector_trajectory_server/target_frame_name: /map * /hector_trajectory_server/trajectory_publish_rate: 0.25 * /hector_trajectory_server/trajectory_update_rate: 4.0 * /rosdistro: kinetic * /rosversion: 1.12.7 * /use_sim_time: True NODES / hector_geotiff_node (hector_geotiff/geotiff_node) hector_mapping (hector_mapping/hector_mapping) hector_trajectory_server (hector_trajectory_server/hector_trajectory_server) map_nav_broadcaster (tf/static_transform_publisher) rviz (rviz/rviz) ROS_MASTER_URI=http://localhost:11311 core service [/rosout] found process[rviz-1]: started with pid [2961] process[hector_mapping-2]: started with pid [2962] process[map_nav_broadcaster-3]: started with pid [2963] process[hector_trajectory_server-4]: started with pid [2964] process[hector_geotiff_node-5]: started with pid [2995] [ INFO] [1516607154.164305614]: Waiting for tf transform data between frames /map and scanmatcher_frame to become available HectorSM map lvl 0: cellLength: 0.05 res x:2048 res y: 2048 HectorSM map lvl 1: cellLength: 0.1 res x:1024 res y: 1024 [INFO] [1516607154.473640201]: HectorSM p_base_frame_: base_link [ INFO] [1516607154.473985848]: HectorSM p_map_frame_: map [ INFO] [1516607154.474065501]: HectorSM p_odom_frame_: nav [ INFO] [1516607154.474138367]: HectorSM p_scan_topic_: scan [ INFO] [1516607154.474426569]: HectorSM p_use_tf_scan_transformation_: true [ INFO] [1516607154.474568112]: HectorSM p_pub_map_odom_transform_: true [ INFO] [1516607154.474655361]: HectorSM p_scan_subscriber_queue_size_: 5 [ INFO] [1516607154.474935408]: HectorSM p_map_pub_period_: 2.000000 [ INFO] [1516607154.475020520]: HectorSM p_update_factor_free_: 0.400000 [ INFO] [1516607154.475194516]: HectorSM p_update_factor_occupied_: 0.900000 [ INFO] [1516607154.475280399]: HectorSM p_map_update_distance_threshold_: 0.400000 [ INFO] [1516607154.475563451]: HectorSM p_map_update_angle_threshold_: 0.060000 [ INFO] [1516607154.475713128]: HectorSM p_laser_z_min_value_: -1.000000 [ INFO] [1516607154.475856377]: HectorSM p_laser_z_max_value_: 1.000000 [ INFO] [1516607154.551815279]: Successfully initialized hector_geotiff MapWriter plugin TrajectoryMapWriter.

I have been trying to figure it out for 3 days now
