Morning all,

I am trying to plot a few msgs on rxplot, which works perfectly fine for 1D. But when I try plotting the covariance matrix given in the message type geometry_msgs/PoseWithCovarianceStamped, nothing is plotted on the screen but my terminal is filled with the covariance values over time, along with the error message: "value was not numeric" . My command looks as follows:

rxplot /< namespace >/ < msg > /pose/covariance

Is there something I have missed? Is it even possible to plot variables of multiple dimensions? I would further like to be able to declare which elements of the matrix to plot (only diagonal values) if it is possible.

Thank you for your help. -A

Good morning all,

I currently have a nodelet that I would like to debug using the following command: "rosrun nodelet nodelet standalone pkg/Type" or just "./ros_mods/nodelet/bin/nodelet standalone pkg/Type" but I am having problems with the initialisation of all my ROS parameters.

What I would like to do is replicate an experiment I logged as a rosbag file, along with a rosparam dump file. I originally tried simply to load the parameters from the dump file (using "rosparam load < dump file >.yaml") then run the nodelet and play the rosbag content.

Now, the nodelet runs without problems and receives the ROS msgs from the rosbag but the rosparams, although loadad an visible when using "rosparam list", are not found by the nodelet. What am I doing wrong? I checked my ROS namespace but everything seemed to be in order. The rosparams (when listed) look identical to when I originally made the experiment and loaded them from a configuration file.

Thank you for your help! -A
