Subplots in rqt_plot

edit

Hi,

I remember in rxplot we could plot several topics either in the same plot, or in multiple subplots. This was achieved by separating the topic names with a comma or with a space.

I wrote a script to help multi-dimensional topic plotting because I was fed up with writing the list of sub-fields or indices. It allows giving only the raw topic name (with or without sub-fields), and the script will build the list of scalars to be plotted, that may come from scalar or array sub-fields.

However I'd like to allow subplotting in order to separate different sub-fields. For example geometry_msgs/Pose has two position and orientation sub-fields and it would be preferable that these two were displayed in separate plots.

It seems that separating fields with comma or space gives the same result in rqt_plot:

rqt_plot robot_pose/position/x,robot_pose/orientation/x
rqt_plot robot_pose/position/x robot_pose/orientation/x

Are there any plans to recover this functionality?
