How to cancel a Navigation point for a while and then start the same point again?

请问如何配置两台Livox_HAP雷达，并在Ubuntu中显示不同的话题？

我在配置两台HAP类型的激光雷达的时候，通过在HAP_config.json中加入两个雷达的ip后，再启动rviz_HAP.launch文件。可以ping通两个雷达，但是rqt_graph里面却只有一个雷达发布话题(另外一个雷达节点存在，没有发布话题)，如下图所示。 配置文件如下图所示。

PluginlibFactory: The plugin for class 'rtabmap_ros/MapGraph' failed to load. Error: According to the loaded plugin descriptions the class rtabmap_ros/MapGraph with base class type rviz::Display does not exist.

I ran into this issue after downloading a navigation package and following the Readme file to execute the mapping command。By the way,it didn't work though I had install rtabmap-rviz packages.
