ROS2 rqt_plot changing axis and creating subplots

[ggershanok-bionaut]

I would like to generate a rqt_plot in ROS2 where the x axis is not the timestamp, but is instead one topics and the y axis is another topic. I know this is an option in ROS with rqt_multiplot, but I do not see documentation for a similar use in ROS2.

ex of what I want to do: ros2 run rqt_plot rqt_plot /topic_x_axis /topic_y_axis

I would also like to create subplots where I have multiple topics stacked on top of each other instead of side by side. This is because they share the same timescale.

Do you know if this is possible in ROS2? What command line commands can I use?
