Subplots in rqt_plot

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?

There is no direct support for subplots in rqt_plot. As an alternative, you can start rqt directly and open multiple instances of the rqt_plot plugin to get multiple plots.

rqt_plot is a community package, so you are welcome to contribute subplots if they're useful to you, or open a feature request ticket and wait for someone else from the community to implement it.

Creating subplots via command line arguments seems not (yet) supported.

However, you can do it manually. See this answer for instructions: http://answers.ros.org/question/59251...
