### Plotting lag, jitter, bandwidth and frequency of topics, how to?

I would like to plot the mentioned data during an experiment for one or more topics and nodes.

Is there a way I can do that?

I tried rxplot but it wants a message's field.

I could go as far as writing a node to publish all this data as messages, but since this data is shown (not published) by a mixture of rostopic and tfmonitor how would I go at collecting the data itself?
