Hi. Following the Beginner Level tutorials in sequence and am currently at Tutorial 8. rqt_graph is throwing errors but at Tutorial 6 it didn't. GUI is visible but Node Graph is not.

This is the error output:

andrew@ubuntu:~$ rosrun rqt_graph rqt_graph
PluginHandlerDirect._restore_settings() plugin "rqt_graph/RosGraph#0" raised an exception:

Well, sometimes if you close the rqt in a worry way , the rqt file in your system will be damaged. So , you can install rqt again.

sudo apt-get install ros-%YOUR_ROS_DISTRO%-rqt ros-%YOUR_ROS_DISTRO%-rqt-common-plugins

Reinstalling rqt does not affect the stored configuration. If the configuration might be the reason for a problem (which I doubt in this case) you can clear it by calling: rqt --clear-config
