rqt_plot not showing data while using rosbags
Hello everyone,
I have a question regarding rqt_plot. The problem is that rqt_plot is not showing the data which is published by a node, but I can see the published data when I run rostopic echo <topic_name>
I think I am doing something wrong with the sim_time, but I am not sure what is wrong. Here is what I am doing:
$roscore$rosparam set use_sim_time true$rosbag play --clock <filename>.bag$rosrun <package> <executable>- Start rqt_plot
Am I missing a step or something?
Thank you very much in advance!
Best regards
Hi @SK,
For what I understand from the set of commands you posted is that you are trying to plot a topic produced by the Node launched at step 4.; not a topic from a Rosbag. If I am mistaken please correct me. However, if that is the case, setting
sim_timeparameter atrueand trying to plot a value produced with a Node in actual time maybe be the reason why you cannot see the the info plotted.
