I can't use rviz in host PC

edit

My purpose is executing navigation to my handmade robot. I have 2 PCs. I'd like to see the rviz and set the goal position from host PC remotely. And I 'd like to control remote PC on the robot to execute amcl.launch.

I have already executed amcl.launch remotely on the remote PC, but I couldn't see the map of rviz from host PC. I thought that it looks like rviz didn't get the information of remote PC. Therefore,I executed "rqt_graph"on my host PC, then I could see some nodes. From this result , I found that my host PC and remote PC are capable of communicating each other.

Please let me know how to see the rviz from my host PC?

Edit: I configured commands as the following procedure.

[1] setting of IP Address and name

on Host(NotePC)
I executed "sudo gedit /etc/hosts" and save the following parameter
    192.168.122.22 NotePC
    192.168.122.33 mori

on remote PC(mori)
I executed same command.
    192.168.122.22 NotePC
    192.168.122.33 mori

[2] start roscore I executed the following command to start roscore in host(NotePC)

export ROS_HOSTNAME=Notepc 
export ROS_MASTER_URI=http://192.168.122.22:11311 
export ROS_IP=192.168.122.22 
roscore

[3] connect to remotePC

ssh mori@mori -p 22
export ROS_HOSTNAME=mori
export ROS_MASTER_URI=http://192.168.122.22:11311 
export ROS_IP=192.168.122.33 
sudo chmod 666 /dev/ttyUSB0
roslaunch  myrobo_navigation amcl.launch

[4] rqt_graph

export ROS_HOSTNAME=Notepc 
export ROS_MASTER_URI=http://192.168.122.22:11311 
export ROS_IP=192.168.122.22 
rqt_graph

Then, The diagram is appeared the following. And I can't see the tf(I also checked it by executing "rosrun tf view_frames").

If I execute roscore and the step [3] only on the remote PC . I can get the following diagram. And I can see tf tree and rviz.

My launch file "amcl.launch" is the following:
