2012-03-26 18:03:25 -0600	asked a question	Why rxgraph show partial information when selecting the combo box? Hi~ I used rxgraph to see how gazebo works, and I found a weird thing. It showed all topics connecting to the gazebo node when I didn't select any PATH combo box. But when I selected the gazebo node of PATH combo box, it just showed little parts of all topics which connecting the gazebo node. http://imgur.com/a/yGtDU I am wondering why this happens. Thanks in advance.
