No point cloud data in Rviz

[TGBoat000]

My lidar is livox MID360. After executing commands in readme.txt, no point cloud data is displayed in Rviz when launching (but success in the livox_ros_driver 2). I have tried in both 22.04 (ROS2 humble) and 20.04 (ROS1 noetic), but the situation are the same. Please help me!

here some advice you can take

1. make sure the topic names（lidar and imu）are correctly set;
2. check the two function (PointLIOROS::imuCallback | PointLIOROS::lidarCallback), make sure this two type of data are handled
3. if you launch "msg_MID360.launch" please set lidar's publish frequency to be 100()
