3D plot from geometry_msgs/Pose message

edit

Hello,

I'm trying to make a 3D plot from data collected by a kinect. For this I recorded a bag file and can echo the topic using:

$ rostopic echo mono_depth_odometer/pose

Which outputs a message like this:

    ---
header: 
  seq: 66
  stamp: 
    secs: 1373486339
    nsecs: 909821489
  frame_id: /base_link
pose: 
  position: 
    x: 3.7901529439e-05
    y: 5.22536844969e-05
    z: 0.000106685859698
  orientation: 
    x: 7.32867424846e-06
    y: -2.76516487714e-06
    z: -8.7403562356e-06
    w: 0.999999999931
---

Now I would like to plot this in 3D. I have succesfully done this before with

rxplot --mode=3d topic1 topic2 topic3

So now I've tried this with different combinations with no success, for example:

$ rxplot --mode=3d mono_depth_odometer/position/x mono_depth_odometer/position/y mono_depth_odometer/position/z
$ rxplot --mode=3d mono_depth_odometer/position.x mono_depth_odometer/position.y mono_depth_odometer/position.z

What is the correct way to access the axis data in the message?

Thank you,
