2019-09-25 10:45:06 -0500	marked best answer	How to plot the position of ethzasl_ptam in rqt_plot ? I have a ROS node (ethz-ptam) which publishes a topic `/vslam/pose` which is of type `geometry_msgs/PoseWithCovariance` message. Running: `rostopic type /vslam/pose \| rosmsg show` gives the following: `std_msgs/Header header uint32 seq time stamp string frame_id geometry_msgs/PoseWithCovariance pose geometry_msgs/Pose pose geometry_msgs/Point position float64 x float64 y float64 z geometry_msgs/Quaternion orientation float64 x float64 y float64 z float64 w float64[36] covariance` I'd like to use rqt_plot to plot a field (say Point position `x`). But I tried everything to "call" it in rqt_plot, but it doesn't work, the rqt_plot window shows like it should but the field is not plotted. From `rostopic echo /vslam/pose` I know that it is being published, so everything is working except rqt_plot. Also if I write inside the text-input-field in rqt_plot, like they say in the docs (`topic-name/field:field:field`): `/vslam/pose/x` or `/vslam/pose/x:y:z` nothing shows. According to the tutorials, in rqt_plot you should be able to hit the `+`Button next to the text-input-field, but this one is never active in my case, so it can't be pressed. I am pretty sure that I am making some kind of mistake in referencing the message field (like `x`). But since I tried all variants I could think of, I'd really apprechiate some advice on how to do this and call/reference this field so that the position fields are displayed in rqt_plot. Thanks!
